What is Cristobalite?

Cristobalite is a mineral composed primarily of silicon dioxide (SiO₂). Due to its high whiteness, low impurity levels and unique physical properties, cristobalite is widely used in applications where appearance, quality and performance are of significant importance.

For products requiring bright colour, high purity and low iron content, cristobalite offers important advantages over conventional mineral fillers.
