Tantalum Carbide (TaC) Powder (Nanopowder and submicrons)
Tantalum Carbide (TaC) Powder is a refractory ceramic material composed of tantalum and carbon. Tantalum Carbide (TaC) are availiable in nanopowder, submicron particles, and micron powder form. Super-fine Tantalum Carbide submicrons are usually manufactured via Vapor-Phase Synthesis and TaC nanoparticles are produced via Spark Plasma Sintering (SPS). TaC powder is used as an additive in tungsten carbide cutting tools, as a coating to prevent erosion and oxidation, and as a component in 3D printing materials.
Princeton Powder is a leading supplier of Tantalum Carbide refractory ceramic powder. Tantalum powders including Tantalum Nanoparticles, Tantalum Tungsten gas atomized powder, and Tantalum Disilicide powder are for sale in bulk.

Tantalum Carbide (TaC) Powder Description
Tantalum Carbide (TaC) is a refractory ceramic material known for its extreme hardness and high melting point. Tantalum Carbide (TaC) powder is an ultra-high melting point material (~3880°C) with exceptional hardness (16-20 GPa), high density (14.5-14.7 g/cm³), and excellent thermal conductivity (~22 W/m·K). It’s commonly used in various high-temperature applications, including cutting tools, abrasives, and coatings.
Tantalum Carbide powder is available in various grades, including different particle sizes and purities, depending on the application requirements.
Tantalum Carbide Powder Manufacturing method (Vapor-Phase and Spark Plasma Sintering)
- Vapor-Phase Synthesis: Tantalum halides (e.g., TaCl₅) and hydrocarbon gases are reacted at high temperatures, producing ultra-fine submicron TaC particles with controlled size and purity.
- Spark Plasma Sintering (SPS): This method combines mechanical and thermal processes to produce dense TaC nanopowders with minimal grain growth.
- Mechanical Milling: For specific applications, powders are further refined through ball milling to achieve uniform particle distribution in the nano or submicron range.
Each process is tailored to meet application-specific requirements such as particle size, morphology, and purity.

Synthesis of ultra-fine tantalum carbide powders by a combinational method of sol–gel and spark plasma sintering
Abstract: A variety of methods have been reported for the preparation of TaC powders, such as self-propagating-high-temperature synthesis (SHS) [6], molten salt synthesis [7], metal thermal reduction [8], [9], sol-gel process [10], [11], [12], liquid precursor conversion method [13], [14] and chemical vapor deposition (CVD) [15]. Among these methods, the sol–gel process is an effective method to obtain ultra-fine TaC powders because of the intimate contact of the reagents at a molecular or colloidal scale [10]. Yan et al. [11] synthesized TaC powders with a particle size of about 30 nm at 1500 °C using tantalum alkoxide, allyl-functional novolac resin and acetylacetone as raw materials.
