The crystals of evening line stone are columnar or needle-like, and these crystals are often fibrous or radial together, with silk luster or glass luster. When heated, It can become mullite and is used as a high-grade refractory. Evening kyanite clan high aluminum line stone, is a kind of important nonmetallic mineral materials, with high thermal stability, the folding resistance and slag resistance, are widely used in high-grade refractory materials, acid materials, technical ceramics, silicon aluminum alloy and synthetic mullite, colour and lustre is gorgeous, can be used as a gem raw materials, single crystal faceted gems, can be milled into the domestic market for silicon line stone cat's eye. In addition, yuxi stone has low porosity, corrosion resistance and abrasion resistance, and is the aggregate of denture casting, bone graft and broken bone joint plate.
