High Purity Tantalum Boride TaB2 Powder CAS 12007-35-1, 99%

Tantalum Boride Powder
tantalum diboride or tantalum boride is gray powder. The Tantalum diboride has a pH of and is insoluble in nitric, hydrofluoric or acid. strong>Tantalum diboride is/strong> completely insoluble in acid, nitric acid and aqua regia. 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), MGB2, TA5B6(Cmmm), and TA3B4(IMmm).

What is the production process of Tantalum Boride Powder ?
Under vacuum or gas cylinder protection, either the carbon-oxidizing mixture and boron oxide are prepared or the powder is prepared through reaction with boron.
The floating zone method allows for the production of single crystals (about 1cm in diameter and about 6cm in length) of Tab2.
At temperatures over 600degC, TAB (single-phase), a mixture of Tacl-5-Bcl3 and H-2-Ar can be used to deposit a tantalum boride film.
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 of Tantalum Boride TAB2 Powder
Tantalum boride, which is composed of tantalum boron is a compound that is noted for having an extremely high degree of hardness. Due to its hardness, tantalum boride can be applied as high temperature materials and abrasives as well wear-resistant coatings.
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 a thermal and electrical conductivity. It is used by the chemical, metallurgical, 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:
