Ceramic fibers are usually made of inorganic materials such as alumina and silicate. In addition, Kerui high temperature ceramics through a special spinning process. Moreover, there are various types of ceramic fiber products. Common high temp ceramic insulation products mainly include ceramic fiber board, ceramic fiber blanket, ceramic fiber module, ceramic fiber rope, ceramic fiber tube and ceramic fiber paper. If you need a certain type of ceramic fiber product, you can contact us.

In addition, you may wonder what temperature can ceramic withstand. The high temperature resistance of high heat ceramic products depends on their specific material composition and manufacturing process. Different types of high temp ceramic products have different maximum high temperature resistance. Generally speaking, Kerui ceramic temperature resistance can withstand high temperatures ranging from 650℃(1202℉) to 1430℃(2606℉). For example, alumina fibers can typically withstand high temperatures up to about 1430℃. Silicate fibers can usually withstand high temperatures between 1000℃(1832℉) and 1400℃(2552℉).

Application of High Temperature Ceramic Insulation

Furnace Lining

The ceramic fiber module or board made of high heat ceramic can be used as furnace lining materials. Such as industrial furnaces, glass kilns, oil refining furnaces and casting furnaces. They are able to withstand high temperatures and chemical corrosion, protecting the furnace structure from damage.

Glass Manufacturing

Excellent high temperature ceramic insulation is often used for thermal insulation and insulation during the glass manufacturing process. Such as glass kiln linings and heat shields. That is, they can withstand high-temperature glass melting processes, reduce energy losses and increase production efficiency.

Metal Smelting

We also use high heat ceramic extensively in metal smelting and casting processes. For example, it is used in thermal insulation layers, thermal insulation layers and filter layers. So, they can withstand the action of high-temperature molten metal, reduce energy loss and improve smelting efficiency.

Other Uses

High temperature ceramic fiber products can also be used in high-temperature equipment in petrochemical, electric power, chemical industry, oil drilling and other industries. Generally, Kerui ceramic fiber products can perfectly provide thermal insulation, heat preservation and fire-resistant protection.
