Ceramsite sand
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.

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.
• Application
  Zircon Sand is used for refractory materials (called zirconium refractories, such as zirconium corundum bricks, zirconium refractory fibers), foundry sand for casting (precision casting sand), precision enamelware, and also for glass and metal (sponge) Zirconium) and zirconium compounds (zirconium dioxide, zirconium oxychloride, sodium zirconate, potassium fluorozirconate, zirconium sulfate, etc.) are produced.
  Packaging & Shipping
• 2. Iron and steel melting, cement rotary kiln and glass furnace, as the ideal material for manufacturing cast sliding plate, nozzle bricks, ladle bricks and open hearth furnace bricks, as well as the basic material for ecotone bricks of large cement kilns, medium cement kilns, refractory castable materials, and first-class and medium-class kiln furniture
