Overview Of Tantalum Boride TaB2 Powder

Tantalum diboride is a gray powder. Tantalum diboride is completely insoluble in acid, nitric acid and aqua regia. Slightly soluble in hot sulfuric acid and hydrofluoric acid, soluble in molten alkali and sodium carbonate. The Vickers hardness of the TaB2 film and crystal is about 30 GPa.These materials are stable to oxidation and acid corrosion up to 700°C.

TaB2 has the same hexagonal structure as most diborides (Alb 2, MGB2, etc.).It also has the following space groups: TAB (orthogonal-crystal system, iodized ((I), Cmcm), TA5B6 (Cmmm), TA3B4 (IMmm), TAB2 (hexagonal, aluminum diboride) type, P6 / mm2).

How is Tantalum Boride TaB2 Powder produced

Under vacuum or cylinder gas protection, the powder is prepared by reacting with the element boron, or the mixture of carbon and oxidizing load and boron oxide is made.

Single crystals of Tab2 (about 1 cm in diameter and 6 cm in length) can be produced by the floating zone method.

Tantalum boride films can be deposited from gas mixtures of Tacl 5-Bcl3-H 2-Ar at temperatures of 540 — 800 °C.TAB 2 (single phase) is deposited at a feedstock gas flow ratio of six (BCL 3 / TACL 5) and at temperatures above 600°C.TAB (single-phase) was deposited at BCl 3 / TaCl 5 = 2-4 and T = 600-700°C.

Tab2 nanocrystals were successfully synthesized by reducing NaBH 4 to Ta 2O 5 with a molar ratio of 1:4 M: B at 700-900°C under argon.

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

Applications Of Tantalum Boride TaB2 Powder

Tantalum boride is a compound of tantalum and boron and is noted for its extremely high hardness. Due to its high hardness, tantalum diboride can be used as high-temperature materials and abrasives, as well as wear-resistant coatings, semiconductor films, electronic materials, ceramic materials, rare earth materials, alloy materials, etc.

Tantalum diboride is a metallic luster crystal with a high melting point, wear-resistance and hardness. It is widely used in the fields of ultra-high temperature ceramic materials, hard materials or composite material reinforcement.

Tantalum diboride also has thermal and electrical conductivity and is used in the chemical industry, metallurgy, building materials, defense industry, agriculture and other departments.

FAQ

Q1

What is TaB2 material?

Answer: Tantalum Diboride (TaB2) Powder (CAS 12007-35-1) is a kind of gray powder with a molecular formula of TaB2. The powder is completely insoluble in hydrochloric acid, nitric acid and aqua regia, slightly soluble in hot sulfuric acid and hydrofluoric acid, and soluble in molten alkali and sodium carbonate.

Q2

What is the hardness of tantalum boride?

Answer: The Vickers hardness of TaB and TaB2 films and crystals is ~30 GPa. Those materials are stable to oxidation below 700 °C and to acid corrosion. TaB2 has the same hexagonal structure as most diborides (AlB2, MgB2, etc.).
