(Ta,Nb)C products details

(Ta,Nb)C tantalum niobium multiple carbide solid solution powder, formula: (Ta,Nb)C, light brown metal cubic crystalline powder, It is composed of tantalum carbide and niobium carbide. Langfeng Material took the unique solid heat treatment, the TaNbC POWDER WE made has the advantages of stable phase composition, uniform grain distribution, high solid solubility, less impurities, uniform particle size and other advantages. Our hot ratio is (Ta, Nb) C 60:40, (Ta, Nb) C 80:20, could produce according to the specific requirements from customers side.


Advantage: Why Langfeng Material’s carbide powder is better:
1. use high purity raw material: tantalum oxide, niobium oxide, carbon black powder. Strictly control in raw material ensure the high purity of end product: tantalum carbide niobium carbide solid solution powder;
2. unique additive application ensure powder grain densification, fairly well carburizing sintering, well-distributed grain;
3. unique sintering process ensure single phase solid solution, low oxygen and low free carbon content, which bring high and stablequality;

 

products application

(Ta,Nb)C tantalum niobium multiple carbide solid solution powder is commonly used as grain inhibitor and grain finer in cemented carbide products, like cutting tools, enhance the tools’ hardness and wear resistance, toughness and stength. Tantalum Niobium carbide powder is also widely used in the fields of thermal spraying, plasma spraying, hard film, conducting.

(Ta,Nb)C products applications

(Ta,Nb)C tantalum niobium multiple carbide solid solution powder is used as additives mainly for P-type cutting tools and cermets because of the beneficial effect on hot hardness and toughness. Tantalum Niobium Carbide (TaNbC) are usually used as an additive to WC-Co ready-to-press (Tungsten-Carbide-Cobalt RTP) grade powders in order to enhance the physical properties of the sintered structure of hardmetals and alloys. TaNbC is frequently used in steel cutting grade powder attritions to maintain structure edge strength at high temperatures.
