Tungsten silicide powder is a gray-black intermetallic compound powder with excellent oxidation resistance, high temperature stability and good electrical and thermal conductivity. Its high melting point, high hardness and chemical inertness make it an ideal choice for plasma spraying, thermal barrier coatings and ceramic reinforcement materials.
We provide tungsten silicide powders in different particle size ranges, and the particle size distribution and purity can be customized according to customer needs. All products are strictly screened and quality controlled to ensure performance consistency and application reliability.
Purity: 99% to 99.5%
Excellent high temperature oxidation resistance (>1000°C)
Good electrical and thermal conductivity
Strong chemical stability, suitable for use in inert or vacuum environments
High temperature oxidation resistance coating: used to prepare high temperature resistant and corrosion resistant coatings in aerospace, heat treatment equipment, heating elements and other fields.
Electronic ceramic additives: as a conductive phase or reinforcement phase in functional ceramics to improve overall performance.
Plasma spray materials: used for intermetallic ceramic coatings in plasma or flame spray processes.
Composite material reinforcement: Added as a reinforcement component to C/C composite materials or ceramic matrix composite materials to improve mechanical and thermal stability.
We provide a complete certificate of analysis (COA) and material safety data sheet (MSDS) for each batch of products, and can arrange third-party testing according to customer requirements to ensure that the data is authentic and reliable, meeting the dual needs of R&D and production.
