Tantalum Boride powder preparation method
Tantalum-Boride Powder is produced by thermal reduction Tantalum Penoxide powder with carbon black or graphite. The reaction equation is: 2Ta205+B4C+15C+2B203=4TaB2+16C0. The reaction is controlled by the material diffusion. The disadvantages to this method include the uneven mixing of Tantalum powder with graphite or carbon powder, and the low activity of graphite or carbon powder. Tantalum powder will reduce incompletely and may become an impurity. Tantalum Boride has a carbon black powder or graphite remaining that is low in activity. This powder is also inactive, so a high temperature of >600degC is required to decarburize it and generate carbon monoxide (CO2) or carbon dioxide.
Tantalum, Tantalum alloys and their applications
The pipe is characterized by a high melting point, excellent corrosion resistance and cold working performance. Pipes have a wide range of applications in the chemical, atomic and high temperature industries. These include heat exchangers for chemical processes, condensers and spiral coils. In the chemical, aerospace, high temperature, atomic and energy industries, bar materials are used widely. These include supersonic planes, rocket engines and spacecraft combustion chambers.
