High Temperature Resistance Furniture Stilts , Ceramic Kiln Furniture Black Color
1. Description
SiC-88%, SiO2-10%, Al2O3-.5%. 18% Porosity, Bulk Density is 2.6/g.cm-3. It is an alumino-silicate bonded silicon carbide with unique physical properties unlike any other competitive product available. Their manufacturing process includes blending SiC grains with application specific additives, pressing the mix to the final shape and firing the green body at high temperature in gas fired kilns. During the firing process, a limited oxidation of the SiC occurs and contributes to the development of the silicate bond. They are excellent resistors of salt, soda, and wood alkali attack, and they like reduction. Exceptional bond strength and tightly controlled density give kiln shelves years of stable performance.
Refractory silicon carbide kiln post, also known as carborundum, is a compound of silicon and carbon with a chemical formula SiC. is made through high temperature sintering, adopting the higher quality raw materials. It has characteristics of stable performance, excellent thermal shock resistance, oxidation resistance, long life, thin volume but high bulk density. Its good thermal conductivity can assure to save energy at maximum level.
2. Using area
Our silicon carbide pillar can offer high mechanical strength at high temperature, excellent heat stability, good distortion resistance at high temperature and oxidization resistance. It can be used in high class washing basin, high-class bowl and bowl urinal. Through the burning of 1300° C, it provides high enamel and high abrasion resistance. It can keep gloss and quality for 10 years. Our brand enjoy good reputation in this trade. We are improving our product and introducing green into our sales activity.
