O que é pó de titânio? Quais são os usos do pó de titânio e seus indicadores de pureza

O pó de titânio é um pó cinza prateado que pode queimar em nitrogênio e possui um alto ponto de fusão . titânio pode ser hidrogenado adicionando gás hidrogênio sob alta temperatura no vácuo .} após a inalação de uma grande quantidade de gás hidrogênio, se torna hidrido de titânio, que é facilmente britilizado e é fácil de ser feito em pó {{{{{{{{{{{{{) pó .
The hydrogen content of titanium hydride powder is generally 4%, silver is dark gray, and hydrogen will be released under high temperature. At present, the application of this technology to make "foam aluminum" titanium hydride powder, because of the hydrogen content, needs to be made into pure titanium powder under high temperature and vacuum, and a lot of time is spent vacuuming to reduce it to titanium powder. Titanium powder is stable at room temperature and has strong chemical ability at high temperatures. It can combine with oxygen, carbon, nitrogen, hydrogen, and many other elements. Pure titanium powder has a suction function at high temperatures, so it is used as a "suction agent" in the electronics industry.
Pureza do pó de titânio
Titanium powder includes both 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, (coarse) titanium powder containing titanium greater than (or equal to) 99%, or close to 99%, is called a grade product (including alloy composition if it is titanium alloy powder), and those with lower purity than it are called substandard products. In grade titanium powder, except for special application requirements, it is generally required to use oxygen content to grade (the same as using titanium content), that is, the lower the oxygen content, the higher the quality. Among them, those with oxygen content less than 0 . 15% são frequentemente referidos como pó de titânio de alta qualidade.
O uso de pó de titânio
Titanium powder is widely used. Grade titanium powder has different uses depending on its purity and particle size. It is mainly used as a raw material for powder metallurgy to produce titanium or titanium containing alloys. Other applications include being used as an electric vacuum suction agent, a raw material for solid gong sources in electric vacuum, and a surface coating Material . matérias -primas para adicionar preenchimentos de titânio a plásticos e vários compostos de titânio, como TIB2, TIN, TIC, etc .
O pó de titânio di -hidrogenado pode ser usado como agente de soldagem de cerâmica e metal, material de fonte de hidrogênio puro e catalisador de sinterização em metalurgia em pó .
Titanium powder is also used in "metal additives" 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 O tamanho das partículas é dividido em 40 malha, 60 malha, 80 malha e 100 malha, que podem ser usadas como um "agente de titânio" .
Extra titanium powder is mainly used as a grain refining agent for cast aluminum and as a deflagrating agent for fireworks and fireworks. Titanium powder will produce white sparks during combustion. Titanium powder is flammable when exposed to open flames and strong friction. The commonly used titanium powder for fireworks is 100 mesh for outdoor Use e 200 malha para fogos de artifício de luz fria interna . Quanto maior a pureza, quanto mais branca a faísca .
