What is titanium powder?
What is titanium powder? Titanium powder is a metal element. Titanium powder can be divided into pure titanium powder, alloy titanium powder, hydrogenated titanium powder, metal titanium powder, sponge titanium powder, titanium nitride powder, and carbonized titanium powder. Titanium particles below 0.83mm are called Titanium powder. Titanium powder, titanium hydride powder, the product is silver-gray irregular powder, has a large air absorption capacity, and is flammable under high temperature or electric spark conditions. What are the uses of titanium powder? Titanium powder is mainly used as a grain refiner for cast aluminum and a deflagration agent for fireworks and ceremony flowers. Let's learn about the specific content of titanium powder!
What is titanium powder?
Titanium powder refers to a group of metal titanium particles with a size less than 1mm, which belongs to loose materials, and its performance combines the characteristics of the titanium matrix and the commonality of the powder. Titanium powder is the same as other powders, its properties include the chemical properties, physical properties and process properties of the powder. However, titanium powder and other powders have a common physical characteristic of having a large specific surface, so titanium powder also has a large surface free energy. Therefore, titanium powder is more active than metal titanium, more likely to react with other elements or compounds, more prone to oxidation, flammable, explosive, and belongs to a dangerous product. Its purity and various properties largely depend on the preparation method and its process conditions.
Titanium powder is silver-gray powder, which can burn in nitrogen and has a high melting point. Titanium can be hydrogenated by adding hydrogen gas under vacuum and high temperature. After inhaling a large amount of hydrogen gas, it becomes titanium hydride. Titanium hydride is easy to embrittle and can be easily made into powder. It is a common method for mass production of titanium powder.
Titanium hydride powder generally contains 4% hydrogen and is silvery dark gray. It will release hydrogen gas at high temperature. Currently, this technology is used to make "foam aluminum" titanium hydride powder. Because of the hydrogen content, it needs to be made into pure titanium powder after high temperature and vacuum. Time to vacuum, reduced to titanium powder. Titanium powder is stable at room temperature, and has strong chemical combination ability at high temperature, and can combine with oxygen, carbon, nitrogen, hydrogen and many other elements. Pure titanium powder has a getter function at high temperature, so pure titanium powder is used as a "getter" in the electronics industry.
The purity of titanium powder
Titanium powder includes titanium content and impurity content. The purity of titanium powder is related to its particle size. For products of the same specification, the smaller the particle size, the lower the purity. Generally, the (coarse) titanium powder containing more than (or equal to) 99% or close to 99% of titanium is called grade product (if it is titanium alloy powder, it should include alloy composition), and the one with lower purity is called subgrade product. In grade titanium powder, in addition to special application requirements, it is generally required to use the oxygen content to classify (the same as the titanium content), that is, the lower the oxygen content, the higher the quality, and the oxygen content is usually less than 0.15% is called high-quality titanium powder.
What are the uses of titanium powder?
Titanium powder is widely used. Grade titanium powder has different uses according to different purity and particle size. It is mainly used as raw material for producing titanium or titanium-containing alloys by powder metallurgy. Other applications are used as electric vacuum getters, raw materials for solid sources in electric vacuum, and surface coating materials. Titanium fillers for plastics and raw materials for various titanium compounds (such as TiB2, TiN, TiC, etc.).
Dihydrogenated titanium powder can be used as ceramic and metal welding agent, pure hydrogen source material and powder metallurgy sintering catalyst, etc.
Titanium powder is also used in "metal additives". It is used as a titanium agent. As an additive, titanium powder can be divided into titanium content: Ti≥88%Ti≥90%Ti≥92%Ti≥95%Ti≥97%Ti≥98 %. The particle size is divided into 40 mesh, 60 mesh, 80 mesh and 100 mesh, which can be used as "titanium agent".
Titanium powder is mainly used as a grain refiner for cast aluminum and a deflagration agent for fireworks and ceremony flowers. Titanium powder will emit white sparks during combustion. Titanium powder is flammable in case of open flame and strong friction. The commonly used titanium powder for fireworks is 100 mesh for outdoor and 200 mesh for indoor cold light fireworks. The higher the purity, the whiter the spark.
