Cordierite mullite saggar is a special 내화물, mainly composed of two minerals, 근청석 (근청석) and mullite (멀라이트). It is usually used in high-temperature furnaces and is particularly suitable for calcining some special ceramic raw materials and materials. Its special properties make it an ideal choice for many high-temperature and high-demand environments, especially in electronic ceramics, special ceramics, 야금, and chemical industries.
Brief introduction of kiln furniture
Kiln furniture refers to refractory products that are recycled in industrial kilns to support or protect the fired products. Kiln furniture must have excellent thermal shock resistance and oxidation resistance. Cordierite-mullite kiln furniture has the advantages of high strength of mullite and good thermal shock resistance of cordierite and has better oxidation resistance than silicon carbide kiln furniture, so it is widely used in the general ceramic industry.
