Spodumene belongs to monoclinic crystal system, and the crystals are usually columnar, granular or plate-like. Color is gray, grey-green, purple or yellow, hardness 6.5-7, density 3.03-3.22g/cm³. As raw material of lithium chemical products, it is widely used in lithium chemical industry, glass, ceramic industry, and enjoys the reputation of "industrial MONOsodium glutamate".
The application of spodumene in ceramics, metallurgy, porcelain picking, special glass, chemical industry is developing rapidly and expanding day by day. According to the use, chemical composition and smelting process requirements, spodumene is divided into three categories: chemical spodumene, ceramic spodumene and low iron spodumene.
Gan mai spodumene yw prif ffynhonnell mwynau diwydiant lithiwm, fe'i defnyddir hefyd i wneud deunyddiau crai cemegol. Megis cynhyrchu lithiwm hydrocsid, gan gynnwys gofannu, trwytholchi dŵr poeth, anweddiad - proses grisialu; Mae rhai yn llosgi spodumene yn gyntaf, ac yna'n adweithio ag asid sylffwrig i gynhyrchu sylffad lithiwm, neu'n defnyddio soda i'w drawsnewid yn lithiwm carbonad. Gellir cael metel lithiwm o gyfansoddion lithiwm syml trwy electrolysis. Defnyddir carbonad lithiwm hefyd mewn diwydiant alwminiwm ar gyfradd gynyddol. Pan ychwanegir cell lleihau alwminiwm, cynyddir dargludedd bath tawdd, gostyngir y tymheredd gweithredu a chynyddir yr allbwn.
