Ceramsite is 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.
1.Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin level
2.Smooth surface of spherical shape greatly improves collapsibility after pouring
3.Low gas evolution and high permeability ensures fewer or no defects
4.High refractoriness and little thermal expansion ensures no burn-on and deformation
5.Artificial sand ensures stable chemical and physical properties
6.Almost neutral PH value allows both acid and basic binder.
7.High durability ensures high reusability.
