evil eye wholesale jewelry Titanium is a transitional metal, and people have always thought it was a rare metal for a period of time. Since the 1940s, titanium and its compounds have been widely used in aircraft, rockets, missiles, artificial satellites, spacecraft, ships, military, medical, and petrochemical industry. The advantages of small density and corrosion resistance; titanium appearance looks like steel and has silver gray translation. The intensity of titanium is large, and titanium alloy resistance reaches 180kg/mm3. The characteristics of titanium are small density (4.51g/cm3), high hardness, high melting point (1675 ° C), and high purity titanium have good plasticity, but when there is impurities, it becomes crispy and hard. During room temperature, titanium does not work with chlorine, dilute sulfuric acid, dilute hydrochloric acid, and nitric acid, but can be eroded by hydrofluoric acid, phosphate, and melting alkali. Titanium is easily dissolved in H2SO4. The most prominent performance of titanium is to have strong corrosion resistance to seawater. Titanium accounts for about 0.42%of the total weight in the crust, ranking seventh in the metal world, and more than 70 minerals containing titanium. At present, the use of titanium has developed rapidly and has been widely used in aircraft, rockets, missiles, artificial satellites, spacecraft, ships, military, light industry, chemical, textile, medical and petrochemical and other fields.
The extremely fine titanium powder is the good fuel of the rocket; the corrosion resistance of titanium is 15 times stronger than the commonly used stainless steel, and the service life is more than 10 times longer than the stainless steel. The application of titanium in surgery is also very fascinating. At present, the surgical bone is used to use stainless steel. There is a disadvantage of using stainless steel. It is very painful to take out stainless steel sheets after the bone healing. Otherwise, stainless steel will harm the human body due to rust. If the titanium "artificial bone" is switched to the orthopedic technology, it will completely change the orthopedic technology. In the place where the head is damaged, use titanium tablets and titanium screws. After a few months, the bones will grow again in small holes and screws of titanium tablets. The new muscle fibers will be wrapped on the titanium sheet. The bones are connected with flesh and blood, play a supporting and reinforcement role. Therefore, titanium is praised as "biological metal". Now it has begun to be applied to knee joints, shoulder joints, rib joints, skulls, active heart petals, bone fixed clamps, etc.
In the steelmaking industry, a small amount of titanium is a good deoxidation, nitrogen removal and sulfur removal agent. Titanium is a precious white pigment called titanium white. Titanium white has both lead white cover performance and zinc -white durability. It is one of the whitening substances in the world, and titanium white is non -toxic. There are hundreds of thousands of tons of titanium dioxide every year.
It titanium dioxide has a high melting point, and is often used to make fire -resistant glass, glaze, enamel, pottery, high -temperature experimental utensils, etc.
Titanium tetrachloride will emerge in a large amount of white smoke in wet air. Because it has this characteristic, it is often used as an artificial smoke in military. Especially in the ocean, there are more water vapor, and one tetrachloride is placed. The thick smoke is like a white Great Wall, which blocks the enemy's sight.
The titanate crystals are widely used in ultrasonic instruments and underwater detectors. This is because when the shape of the pressure is changed, the current will generate; once the power is powered, it will change the shape. Putting titanic acid in the ultrasonic wave, it will generate current by pressure. The size of the current generated by it can measure the strength of the ultrasonic wave; on the contrary, the ultrasonic can be generated by passing it with high frequency current.
In gold decorative crafts and daily necessities, because of their low hardness, easy piercing and wear, they cannot be durable. When plating a layer of titanium nitride on the surface of these substances, the appearance is almost exactly the same as the coating of gold, and it is more abrasion than gold and hard alloy. This coating is known as "never wear".
organic titanium polymer can be used as a surfactant, dispersing agent, water antidote or rust -proof agent.
M of the four series of hydrogen storage metals used by humans, titanium is one of them and is also cheaper, but at present humans have not found a more ideal "hydrogen storage metal". Once this problem is solved, it solves this problem. For people, people can use hydrogen for fuel.
"titanium aircraft" can reduce the body weight of 5 tons and more than 100 passengers. In the new type of jet engine, titanium alloy has accounted for 18 to 25 % of the weight of the entire engine; on the latest supersonic aircraft, the use of titanium accounted for almost 95 % of the total weight of the entire body structure. It is difficult to develop the current supersonic aircraft.
The submarine made of titanium is not only durable than steel submarines, but also can sneak into a larger depth. Titanium submarines can submerge below 4,500 meters. This is the boundary between steel submarines that cannot be passed. Make warships and ships with titanium, without painting, and sail in seawater for several years will not rust. Because titanium is not a ferromagnetic substance, it will not be discovered by magnetic water mine. This is particularly important in the military. If there is no heating steel made of titanium, the life of the conventional weapon rifles and machine guns currently used can only be the original 4.5 seconds. Essence
The strong absorption of titanium and 锆 to the air can remove the air and cause vacuum. The vacuum pump made of titanium alloy can draw the air to only one billion yuan.
The titanium alloy is an ideal superconducting material. Tsinghua University uses the principle of optical interference and ionic titanium nitride treatment to make a clear and layered mountain ink painting.
Among the two most common stainless steels currently used, type 18-8-1 of chromium nickel titanium (18%chromium, 8%nickel, and titanium 1%) is the most commonly used industry.
Ti titanium titanium (TIC) is quite carbide, with metal luster. But it has higher melting points and higher hardness than carbonized iron. Therefore, it has practical application value.
The food preserved with titanium -made utensils, color, fragrance, and taste is enduring; titanium cooking utensils are lightweight and not rust, and are the most scientific and hygienic.
The high -pressure container made of titanium alloy can tolerate 2,500 atmospheric pressure.
This alloys composed of titanium and nickel have become "memory alloys". This alloy is made into a pre -determined shape, and after being treated, if it is deformed by external forces, as long as it is slightly heated, the original appearance can be restored. This alloy has been applied in many fields. For example, the antenna used on the Apollo spacecraft is this kind of memory alloys; the Ninth People's Hospital of Shanghai First Medical College has used this memory alloy in women's sterilization surgery; in addition, it can be used in the fields of instrument, electronic device and other fields Essence
The biggest obstacle to the widespread use of titanium is difficult to smelter. Because the melting point of titanium is very high, the titanium titanium must be performed at higher temperatures, and the chemical properties of titanium at high temperature become very lively. Therefore This puts forward high requirements for smelting equipment and craftsmanship. At present, about 70%of the smelting titanium is used in manufacturing aircraft, missiles, spacecraft, and artificial satellites.
This of the titanium titanium is countless, so titanium is awarded the title of "21st Century Metal"
