Tantalum Hafnium Carbide powder is an ultra-high-temperature ceramic (UHTC) material based on a tantalum carbide-hafnium carbide system. It exhibits excellent thermal stability, corrosion resistance, and mechanical strength, making it widely used in high-performance structural components and thin-film deposition applications in extreme environments.
We offer high-purity, uniformly sized Tantalum Hafnium Carbide powder to meet diverse needs, from research experiments to industrial production. Customized particle size ranges and distributions are also available.
Purity: 99.9%
Uniform particle size distribution and excellent flowability
Customizable packaging
Excellent thermal stability, suitable for high-temperature and high-pressure environments
Suitable for a variety of applications, including ceramic-based composites and PVD/CVD coatings
Aerospace: Used as thermal barrier coatings or thermal protection systems in extreme heat flux environments, such as missile nose cones and engine nozzles.
High-temperature structural ceramics: Added to ceramic composites to improve overall mechanical properties and thermal shock resistance.
Thin-film deposition: Used as coating targets or powder targets to deposit high-temperature, wear-resistant thin films in CVD/PVD systems. Nuclear Industry: It exhibits excellent neutron absorption and radiation resistance, making it a potential material for nuclear fuel cladding.
Each batch of Ta4HfC5 powder comes with a Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and relevant testing data. We support third-party inspections and provide pre-sales technical consultation and after-sales user guidance to help you optimize process parameters and application solutions.
