Production method of tantalum boride TaB2 crystal

Overview of tantalum boride TaB2 powder

Tantalum boride TaB2 has the same hexagonal structure as most diborides (Alb2, MGB2, etc.), and also has the following space groups: TAB (orthogonal system, iodide ((I), Cmcm), TA5B6 (Cmmm)) , TA3B4 (IMmm), TAB2 (hexagonal, aluminum diboride) type, P6/mm2).

The Vickers hardness of TaB and TaB 2 films and crystals is ~30 GPa. These materials are stable to oxidation and acid corrosion below 700 °C. TaB 2 has the same hexagonal structure as most diborides (AlB 2, MgB 2, etc.). The above-mentioned borides have the following space groups: TaB (orthogonal, thallium (I) iodide, Cmcm), Ta 5B 6 (Cmmm), Ta 3 B 4 (Immm), TaB 2 (hexagonal, aluminum diboride) Type, P6/mmm)

Production method of tantalum boride TaB2

TaB, Ta 5 B 6, Ta 3 B 4 or TaB 2 single crystals (about 1 cm in diameter and 6 cm in length) can be produced by the floating zone method.

In the temperature range of 540-800°C, a tantalum boride film can be deposited from a gas mixture of TaCl 5 -BCl 3 -H 2 -Ar. TaB 2 (single phase) is deposited with a source gas flow ratio of 6 (BCl 3/TaCl 5) and a temperature higher than 600°C. TaB (single phase) is deposited at BCl 3/TaCl 5 = 2–4 and T = 600–700 °C. TaB 2 nanocrystals were successfully synthesized by using NaBH 4 to reduce Ta 2 O 5 with NaBH 4, the molar ratio of M:B is 1:4, and it lasts for 30 minutes under argon flow at 700-900 °C.

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 is a compound of tantalum and boron, which has attracted attention due to 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 high melting point, wear resistance and hardness. It is widely used in the reinforcement field of ultra-high temperature ceramic materials, hard materials or composite materials.

Tantalum diboride also has thermal and electrical conductivity, and can be used in chemical, metallurgical, building materials, national defense, agriculture and other sectors.
