      1、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.

      4、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.
