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

Tantalum boride is also known as Tantalum Diboride. Tantalum diboride cannot be dissolved in acid.

Particle Size: 325 Mesh

Tantalum Boride (TB2Powder

Tantalum disboride and tantalum diboride are both gray powders. Tantalum boride is totally insoluble with acid, nitric acids and aqua regia. Hot sulfuric acid and hydrofluoric Acid are slightly insoluble. It is also soluble with molten alkali, sodium carbonate and molecular bicarbonate. Crystal Vickers hardness and TaB2 Film are about 30GPa. These materials can withstand oxidation up to 700degC.

uses the same hexagonal design as many diborides, such as MGB2, Alb 2, and etc. The following space groups are also available: TAB, orthogonal-crystal structure, iodized ((I), MGB2, etc.), TA5B6/Cmmm), and TA3B4/IMmm. TAB2 type (hexagonal diboride, aluminum) is P6 /mm2.

How is Tantalum Boride TAB2 Powder manufactured?

Vacuum or cylinder-gas protection is used to prepare the powder by reacting the element boron or the mixture carbon/oxidizing load or boron oxide.

By using the floating zone technique, single crystals can be made of Tab2 that measure approximately 6cm in length and 1cm in diameter.

Tantalum Boride Films can be produced from mixtures with Tacl 5-Bcl3+H 2-Ar at temperatures between 540 and 800 degrees Celsius.TAB 2 is (single Phase) deposited at BCl3 / TaCl5 = 2-3 and T = 600 to 700degC.

At 700-900degC in argon, Tab2 nanocrystals could be synthesized successfully by reduction of NaBH4 to Ta 2O 5.

Ta 2 O 5 + 6.5 NaBH 4 -2 TAB 2 + 4 Na (G, L) + 2.5 NaBO 2 + 13 H 2 (G)

Tantalum Boride Powder

Tantalum boreide is a combination of tantalum, boron. It is well-known for its extreme hardness. Because of its hardness, tantalum boride can be used in high temperature materials and abrasives as well as wear resistant coatings, semiconductor films electronic materials ceramic materials rare earth metals alloy materials, and other applications.

Tantalum diboride can be described as a metallic, luster crystal that has high melt points and wear resistance. This is a widely-used material in ultra high temperature ceramics, composite materials reinforcement and hard materials.

Tantalum diboride has electrical and thermal conductivity. It is widely used in agriculture, chemical industries, metallurgy and building materials.

Tantalum Boride TaB2 Pulver Storage:

TaB powder’s dispersion performance will be affected by damp reunion. Therefore, tantalum Boride TaB should be vacuum packed and kept in cool, dry place. The tantalum Boride TaB can not be exposed to the air. Additionally, TaB powder should not be exposed to stress.

Packing & Shipping of Tantalum Boride TB2 Powder

We offer many packing options that are dependent on the quantity of tantalum bore TaB powder.

Vacuum packed Tantalum borid TaB powder packaging:100g, 500g and 1kg/bag at 25kg/barrel. Or as you request.
