Lithium Minerals

Spodumene is a pyroxene mineral and a source of lithia. It is used in glasses, ceramics, porcelain enamels, whitewares and glazes due to its powerful fluxing properties. It has low thermal expansion, reduces the melt viscosity, melting temperature and contributes to brilliancy and strength of the glass.

Petalite, also known as castorite, is a lithium aluminum phyllosilicate mineral. It is used in ceramics, glass and enamels. The addition of petalite improves strength, density, acid resistance, heat resistance and gloss. It reduces melt viscosity, melting temperature and thermal expansion and promotes melt homogenization.
