Mullite Sand
Mullite sand is aluminum silicate refractory materials, normally used in stainless steel precision
casting technology. Refractoriness around 1750 degrees, Mullite sand content more aluminum
and lower iron to show that the quality is more better, content lower dust to show that the quality
is more better. Mullite sand is made by kaolin through high heat sintering. Mullite sand origin in
mainly distributed in the zhangqiu shandong and north of anhui and so on.
Mullite sand general type are 8-16 orders, 16-30 mesh, 30-60 mesh, 60-80 mesh, 80-120 mesh;
Mullite powder typeare 200 mesh, 300 mesh, etc.In the precision casting process,
General surface plasma, zirconium powder: 325 mesh + silicon sol sand: zirconium sand 120
mesh Back layer pulp: 325 mesh + silicon sol + mo to powder 200 mesh sand: mullite sand 30
to 60 meshReinforcement layer: mo to powder 200 mesh + colloidal silica sand: mullite sand
