Ceramic Foundry Sand: its characteristics and applications<\/h2>\n\n\n\n

Ceramic Sand has lower cost and better performance than Chromites sand and Zircon sand, it will provide the effective ways to improve the quality of the foundry part, reduce cost and friendly to the environment.<\/p>\n\n\n\n

Ceramic Foundry Sand has advantages as follows:<\/h2>\n\n\n\n
    \n
  1. Round solid Ball shape: The shape is mostly close to ball shape with smooth surface. It has very good liquidity and easy to fill that it can make perfect surface of casting part.<\/li>\n\n\n\n
  2. Lower thermal expansion rate and thermal conductivity.<\/li>\n\n\n\n
  3. Lower breakage rate: it has high density and very low cleavage breakage rate. Easily reclaimed, environmental friendly, less dust.<\/li>\n\n\n\n
  4. High refractoriness and working temperature: The working temperature is beyond 1790\u2103 that can make it possible to found most of the metals.<\/li>\n<\/ol>\n\n\n\n
