When making ceramic fiber shaped parts, the choice of raw materials is very important. So what issues should we pay attention to when choosing?
Variety and performance: The most important indicators of ceramic fiber blankets are fiber diameter and thermal stability.
Al2O3SiO2 fiber is commonly used in the ceramic industry. It is divided into different application ranges according to the content of Al2O3. Cr2O3 material is also introduced to improve its fire resistance and oxidation resistance.
Generally, the fiber products with high alumina content and low impurity content such as iron oxide are pure white, and the fibers with chromium oxide are colored with a creamy yellow tone.
Ceramic fibers have an average diameter of 22-33 microns. Those with fine fiber, low density and low thermal conductivity have high temperature.
