Silicon Carbide Fiber

Name: Silicon Carbide Fiber
Brand: YUSHENG ENTERPRISE LIMITED
Price: 100 USD

Silicon carbide fiber is a high-performance ceramic fiber which has antioxidant property at high temperature, high hardness, high tenacity, high thermal stability, anticorrosion and low density property etc.

The fiber production process mainly adopts pre-somatic transformation method which including pre-somatic synthetic, melting & spinning, infusible treatment and sintering at high temperature, and it is a widely production method at present and suitable for industrial production with mature technology, high production efficiency and low cost.

The manufacturing principle of pre-somatic transformation method is to synthesize pre-somatic (polycarbosilane) from high polymer which containing target element, then the pre-somatic is spun to organic fiber, at last the organic fiber is cross-linked into inorganic ceramic fiber.

Silicon carbide fiber multifilament includes Zeralon200 doped silicon carbide fiber multifilament and Zeralon3A aluminum-doped silicon fiber multifilament.
