FAQs What is the difference between Olivine and Silica Sand? These are both natural deposits. With Olivine, a finer sand may be used due to increased permeability, and thermal expansion is much lower than silica, therefore reducing expansion defects resulting in a smoother casting.
Olivine is a valuable raw material for use in Foundries as Foundry sand for mould construction in both ferrous and non-ferrous metal casting. Foundry sand from Olivine has an uniform low thermal expansion (0,8% at 1300 ˚C) resulting in better casting accuracy and smoother surface.
