Ceramic Fiber Types

What is Ceramic Fiber ?

Ceramic fiber, also known as aluminum silicate fiber, is called ceramic fiber because one of its main components is alumina, and alumina is the main component of porcelain. The addition of zirconia or chromium oxide can further increase the service temperature of ceramic fibers. Ceramic fiber products are an kind of industrial products that use ceramic fiber wool.

Ceramic fiber is a kind of lightweight refractory material, which has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical vibration resistance, so it is widely used in machinery, metallurgy, chemical industry, petroleum, ceramics, glass, etc. , electronics and other industries.

Properties of Ceramic Fiber

  • Flexible,light weight and easy to cut

  • Good insulation performance

  • Very low thermal conductivity,low heat storage and low shot content

  • Good corrosion resistance

  • Precise thickness and accurate sizes

Types of Ceramic Fiber

The varieties of ceramic fibers mainly include: ordinary aluminum silicate fiber, high aluminum aluminum silicate fiber, aluminum silicate fiber (Cr2O3, ZrO2), polycrystalline alumina fiber and polycrystalline mullite fiber. In recent years, the market have successfully developed (or are developing) some new ceramic fiber varieties, such as forsterite fiber, ceramic fiber (SiO2-CaO-MgO system and Al2O3-CaO system) and so on.

The ceramic fiber products including:

Application of Ceramic Fiber
