Spodumene itself is not toxic, so it is used as a pot, mainly depending on whether other substances are added during the production process and whether toxic metal substances are oozing out.

Generally, spodumene casserole is non-toxic and can be used safely. The principle of making spodumene casserole is to add a certain proportion of spodumene to the traditional process, aiming at solving the problem that the pot is easy to crack by using the stability of spodumene.

Casseroles made of spodumene can keep the quality of the pot intact under extremely cold and hot conditions. The probability of heavy metals exceeding the standard in casseroles made of spodumene is not high. As a weakly alkaline crystal ore, spodumene has a low content of heavy metals.

Related applications of spodumene

Spodumene is used in glass and enamel industry. By introducing spodumene into the glaze formula of glass and enamel, two kinds of low expansion crystals, β -spodumene and Kay Yingshi, can be obtained in a wide range of compositions, and the seeds can be uniformly crystallized at the same time without introducing crystal nuclei, thus improving the mechanical strength and thermal shock resistance.

Because spodumene is the most important mineral source in lithium industry, it is also often used to prepare chemical raw materials. For example, lithium hydroxide is produced by a method including calcination, hot water leaching and evaporative crystallization; Others calcine spodumene first, and then react with sulfuric acid to generate lithium sulfate, or convert it into lithium carbonate with soda ash, and simple lithium compounds can be electrolyzed to obtain metallic lithium.

In addition to ceramic industry, spodumene has been used more and more in aluminum industry. Adding it into aluminum reduction electrolyzer can improve the conductivity of molten pool, reduce the operating temperature and increase the output. Pure lithium carbonate has also been successfully used for chemotherapy of madness and depression.
