Product Description:

Ceramic fiber bulk is made of coal gangue by melting at high temperature through resistance furnace, before being blown or spun into fiber.

As a neutral and acidic material, except reaction with the strong acid-alkali, ceramic fiber won’t be eroded by other weak alkali, weak acids, or water, oil, steam, or be infiltrated with lead, aluminum or copper, featuring excellent flexibility and elasticity.

Ceramic Fiber Bulk

Product Description

The polycrystal alumina fiber bulk is made of melted aluminum salt through chemical colloid method.

The solution is heated and inspissated into fiber under specific conditions and got polycrystal alumina fiber after the heat treatment

Ceramic fiber bulk show a high temperature stability.Low weight , heat capacity and an outstanding sound absorption is complemented by their resistance to shock and erosion.
