Selected high purity quartz sand undergoes thermal treatment at 1500oC and catalyzed by the addition of a sodium based flux additive. With this process, Cristobalite is produced. The exceptionally high whiteness, chemical purity, thermal conductivity acid resistance and low density, make cristobalite the ideal filler for various specialised products (paints, coatings, ceramic products, decorative surfaces, silicon products, jewellery, cosmetics etc.).
Our company imports packed Sibelite ® Cristobalite from the established manufacturer Sibelco.
