Tantalum Boride Powder
Tantalum boride or tantalum diboride is a powdery gray color. The Tantalum Diboride has a pH of and is insoluble in nitric, hydrofluoric or acidic solutions. Solvable in molten sodium carbonate and nitric acid. Slightly soluble with hot sulfuric acid. Crystal and TaB2 films have a Vickers Hardness around 30 GPa. These materials are resistant to acid corrosion and oxidation up to 700degC.
TaB2 shares the same hexagonal shape as most diborides. (Alb 2, MGB2,etc.). It also has space groups such as TAB (orthogonal, crystal system, iodized Cmcm ((I), TA5B6-Cmmm), and TA3B4-IMmm, TAB2 type (hexagonal diboride of aluminum, P6/mm2).

How are Tantalum Boride TAB2 Powder manufactured?
The powder is made by reacting boron with carbon or an oxidizing mixture.
The floating zone method allows for the production of single crystals (approximately 1 cm in size and 6 cm long) of Tab2.
At temperatures over 600degC, TAB (single phase), deposited by a ratio of BCL3 / TaCl5, is possible.
Tab2 nanocrystals can be synthesized successfully by reducing NaBH4 to Ta 2O5 with a molecular ratio of 1:14 M:B under argon at 700-900degC.
Ta 2 O 5 + 6.5 NaBH 4 -2 TAB 2 + 4 Na (G, L) + 2.5 NaBO 2 + 13 H 2 (G)
Application Tantalum Boride TaB2 powder
Tantalum boride, which is composed of tantalum boron is a compound that is known for having an extremely high degree of hardness. Due to its hardness, tantalum boride is suitable for high temperature materials and abrasives.
Tantalum diboride, a metallic luster crystalline material with a high melting temperature and wear-resistance, is hard. It is widely applied in ultra-high temperatures ceramic materials, hard material or composite materials reinforcement.
Tantalum Diboride has also thermal and electrical conductivity. It is used by the chemical industry, metallurgy building materials, defence industry, agricultural and other departments.
Store Tantalum Boride TaB2 powder in the following conditions:
TaB powder will be affected by dampness and its effects on dispersion and use if it is not stored in a dry and cool room. TaB should also not be exposed to stress.
Packing & Shipping of Tantalum Boride (TaB2) Powder:
