Pure silica sand is extremely heat resistant and consequently ideal as a mould material for moulds and cores. In consultation with the customer, Sibelco will deliver the required AFS-value and particle shape.

Precision casting according to the lost wax method is realised in forms of mixed cristobalite, quartz and plaster. The high thermal expansion of cristobalite compensates for the shrinkage after cooling. This technique is often used in the production of jewellery but also in dental techniques and in the production of fine mechanical components.
