1. Ceramsite sand Product Introduction
Ceramsiteis a kind of refractory particle with diameter of
0.020mm~2.00mm, mainly made of Al2O3·SiO2. It is ball-shaped
particle made from fine bauxite ,which is fused in high-temperature
electric-arc furnace and sprayed to ball shape.
2. Features of Ceramsite
Perfectly round shape with higher fluidity improves fill-in
efficiency while reducing the resin level
Smooth surface of spherical shape greatly improves collapsibility
after pouring
Low gas evolution and high permeability ensures fewer or no defects
High refractoriness and little thermal expansion ensures no burn-on
and deformation
Artificial sand ensures stable chemical and physical properties
Almost neutral PH value allows both acid and basic binder.
High durability ensures high reusability.
3. Applications of Ceramsite
Used in all types of foundry technique like resin-bonded sand,
sodium silicate sand, and clay-bonded sand.
As core sand for making like jacket core, oil duct core and tappet
core of engine.
Excellent replacement of chromite sand
As dry sand of sand box for EPC process and V method of casting
process.
