Spodumene is the most important industrial mineral and the characteristic mineral in lithium-rich granite pegmatite. It mainly occurs in granite pegmatite veins. Different from other pyroxene minerals, spodumene is a pegmatite mineral, which often coexists with crystal, tourmaline and beryl.

The chemical composition of spodumene is LiAl, in which the theoretical content of Li2O is as high as 8.03%, and the general content of Li2O in spodumene concentrate is 6.3~7.5%. In fact, the content of T is usually between 2.9 1 ~ 7.66%, which may be due to the replacement of lithium by sodium and potassium.

On the basis of traditional casserole technology, a certain proportion of spodumene is added to the material, and the stability and heat resistance of spodumene are used to make up for the shortcomings of traditional casserole that it is easy to crack after dry firing. This kind of casserole is called a new generation of ceramic casserole, and it will not crack when it is burned to 600℃ and put into water at 20℃. The spodumene heat-resistant casserole can be directly barbecued in the microwave oven.

It can also be refrigerated in the refrigerator and fried, stewed and boiled under various heat sources. The test is still intact under the condition of long-term quenching and heating, and it has good thermal stability. At the same time, spodumene belongs to crystalline weakly alkaline ore, which is rich in various minerals and can be decomposed by heating. Cooking food with spodumene in ceramic casserole can supplement trace elements needed by human body and has certain health care function.
