Through many year's innovation and development, this prodcut is one kind of series products based on inorganic material techniques at CCRMM. This product enjoys the following basic features like environmental protection, outstanding function, low-energy consumption, and high cost-effectiveness. It is a new kind of ceramic sand for foundry use based on the application environment design, development and manufacture under the actual high-temperature circumstance of foundry. Compared with the traditional ceramic sand for foundry use, this product is more environment-friendly and better cost-effective; thus, it could be a good substitute for traditional ceramic sand which is made through electric smelting technology.
