What is ceramic fiber cotton?

Ceramic fiber cotton is a high-temperature refractory insulating material made from silica and alumina as the main materials by resist furnace melting. It is also known as ceramic fiber bulk or ceramic cotton. It has the characteristics of being lightweight, high strength, oxidation resistance, low thermal conductivity, good softness, corrosion resistance, small heat capacity, and sound insulation.

Manufacturing of ceramic fiber bulk

Ordinary ceramic fiber cotton is made of hard clay clinker as a raw material, melted in a resistance furnace, and produced by spinning into fibers.

High-alumina ceramic fiber wool uses high-purity alumina silica powder synthetic material as a raw material. It is melted in a resistance furnace and produced using the injection fiber-forming process.

A composite of zirconium-containing ceramic fiber cotton, high-purity alumina silica powder, and zircon yarn, it is melted in a resistance furnace and produced using a fiber spinning process.
