High Quality kaolin sand ceramics price

Mullite is a refractory material with the nature of Aluminium silicate, which is generally used in various precision casting technologies such as stainless steel. The higher the aluminum content in mullite, the lower the iron content in it. The higher the dust, the better the quality of mullite products. Molybdenum sand is formed by sintering aged soil at a certain high temperature. Density ≥ 2.5g/cm3, true specific gravity>2.6g/cm3, moisture content<0.03%, fire resistance ≥ 1750 ℃, ignition loss ≤ 0.3-0.4%, dust content ≤ 0.01-0.03%, pH value 7-9, shell hardness>8.0Mpa.Castings that are easy to shell out, not deformed, not easy to scale, have good smoothness, and high yield. The classification of mullite sand generally includes 8-16 mesh, 16-30 mesh, 30-60 mesh, 60-80 mesh, 80-120 mesh; Molay powder generally has 200 mesh, 300 mesh, etc. In the refined casting process: general surface slurry, zirconium powder: 325 mesh+silica sol? Sand: Zirconium sand 120 mesh…
