2020 Vision: The Near Future of Feldspar and Nepheline Syenite Market
Nepheline syenite is an igneous rock which is formed out of molten magma in the absence of silica. Nepheline syenite is similar to granite and constitutes three types of minerals which are the microcline form of feldspar, the albite form of feldspar and nepheline. Their percentage varies - microline constitutes 25 %, nepheline 22% and albite 55% respectively. In glassmaking, alumina from feldspar enhances durability, product hardness and resistance to chemical corrosion. In ceramics, feldspar is used as a flux,...
