Ceramic Casting Sand Physical and Chemical Properties

Ceramic Casting Sand Applications

  1. Used in all types of foundry techniques like coated sand, resin-bonded sand, sodium silicate sand, and clay-bonded sand.
  2. As molding sand and core-making sand for iron casting, steel casting, and alloy steel casting.
  3. As a substitute for chromite sand for jacket core-making, oil duct core-making, tappet core-making of the engine.
  4. As facing sand for large steel castings.
  5. As dry sand of sandbox for EPC process and V method of casting processes.
