What is ceramic fiber?
Posted by:Rosewool Date:09.Jun.2022
Ceramic fiber is a kind of fibrous 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, electronics and other industries have been widely used. In recent years, due to the continuous rise of global energy prices, energy saving has become China's national strategy. In this context, ceramic fibers that can save 10-30% energy compared with traditional refractory materials such as insulating bricks and castables have been obtained worldwide. More and wider applications, the development prospects are very broad.
Ordinary 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 use temperature of ceramic fibers. Ceramic fiber products refer to industrial products with the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical vibration resistance, which are made of ceramic fiber as raw materials. , high pressure, easy to wear environment. Ceramic fiber products are an excellent refractory material. It has the advantages of light weight, high temperature resistance, small heat capacity, good thermal insulation performance, good high temperature thermal insulation performance, and non-toxicity. There are more than 200 large and small ceramic fiber manufacturers in China, but the production process of ceramic fibers with a classification temperature of 1425°C (including zirconium fibers) and below can only be divided into two types: spinning blankets and blowing blankets.

Properties of Ceramic Fibers
Light weight, good thermal insulation performance, good thermal stability, good chemical stability, easy processing and convenient construction. It is neither wear-resistant nor collision-resistant, cannot resist the erosion of high-speed airflow, and cannot resist the erosion of slag.
