Olivine. Olivine is a high-magnesia asbestos-free, quartz-free, refractory, hard, inert, hydration free mineral produced from intrusive or effusive volcanic rocks (e.g. Forsterite Mg2SiO 4, Fayalite Fe2SiO 4 (Mg, Fe2SiO 4). It has a low degree of thermal dilation. The density and solubility increase and the melting point decreases with increasing iron content.

It is known to use sands in combination with a thermosetting resin binder to make foundry molds. Olivine sands, usually comprising a mixture of magnesium and iron silicates, are normally preferred to silica sands in applications where moderate temperature stability is required for the mold. However, olivine sands have the disadvantage that moldsmade therefrom must either …
