Description of Tantalum Hafnium Carbide (Ta4HfC5) Powder
Tantalum Carbide (TaC) is an hard refractory ceramic material known for its super high melting point of around 3,880°C. It offers excellent resistance to wear, corrosion, and oxidation, making it ideal for high-temperature applications.
Hafnium Carbide (HfC) is a super durable refractory ceramic with an ultra-high melting point of approximately 3,958°C. It is characterized by its outstanding durability and resistance to wear, oxidation, and elevated temperatures. HfC is commonly used in thermally resistant applications.
The properties of Tantalum Hafnium Carbide (Ta4HfC5) powder are largely influenced by its constituent materials, Hafnium Carbide (HfC) and Tantalum Carbide (TaC). Both HfC and TaC have very high thermal melting points, superior durability and ability to withstand corrosion and oxidation, making Ta4HfC5 an excellent material used under extreme high-temperature conditions.

Reference
- Ultra-high temperature ceramics (UHTCs) are refractory transition-metal carbides, nitrides, and borides with the highest melting temperatures known materials, making them prime candidates for applications in aerospace and hypersonic vehicles. Of the UHTCs, tantalum carbide (TaC) and hafnium carbide (HfC) feature the highest melting temperatures. We investigated the binderless consolidation of HfC/TaC powder blends using Field Assisted Sintering Technology (FAST).
By spark plasma sintering. Solid solutions of Tantalum carbide (TaC) and Hafnium carbide (HfC) were synthesized by spark plasma sintering. Five different compositions (pure HfC, HfC-20 vol% TaC, HfC- 50 vol% TaC, HfC- 80 vol% TaC, and pure TaC) were sintered at 1850°C, 60 MPa pressure and a holding time of 10 min without any sintering aids. Near-full density was achieved for all samples, especially in the HfC-contained samples.
Transition metal carbides have gathered increasing attention in energy and electrochemistry applications, mainly due to their high structural and physicochemical properties. Their high refractory properties have made them an ideal candidate coating technology and more recently their electronic similarity to the platinum group has expanded their use to energy and catalysis.
In the atomic energy, tantalum hafnium carbide is used in the construction of parts for warheads, in the electronics industry, in the metallurgical industry where it is used for the creation of very thin flinty layer coatings, which are essential in the mechanization and automation processes in metallurgy.
