Super Ceramic Sand is a man-made spherical particle shape high-end foundry sand. Known by many names including Ceramic Sand, Cerabeads and CeramCast, an excellent choice for the sand casting industry.

One of the main advantages of super ceramic sand is its high refractoriness. In addition, the product has almost no thermal expansion, which means it retains its shape even when there are significant changes in temperature.

Super Ceramic Sand also has an excellent angle factor, which means it flows freely around complex shapes and intricate details. This makes it ideal for complex castings and molds.

Another impressive feature of Super Ceramic Sand is its high recovery rate. This means that the product can be reused many times, which not only reduces waste, but also saves production time and money. The high recovery rate also means the product is environmentally friendly as it minimizes the amount of material that needs to be mined and processed.

In conclusion, Super Ceramic Sand is a game changer for the sand foundry industry. With its high performance and exceptional durability, it is ideal for complex castings and molds. Its high recycling rate and environmental benefits make it a responsible and sustainable choice for manufacturers.
