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.
