Spodumene

详情

Summary

Spodumene is monoclinic crystal shape, often Chengzhu, granular or plate. Color is gray, gray green, purple or yellow, hardness 6.**7, density 3.***3.*2g/cm3. As a raw material for lithium chemical products, widely used in lithium chemical, glass, ceramic industry, enjoy the "industrial monosodium glutamate" in the world.

Use of lithium
Ceramic industry: in the ceramic body adding spodumene can improve ceramic products, the strength, density, acid resistance and thermal shock resistance, can reduce the water absorption rate and linear shrinkage rate. Adding the right amount of spodumene in glazes and frits, can reduce the coefficient of thermal expansion (CTE products, glaze to improve the high temperature flow, reduce the viscosity and improve the glazed whiteness, gloss, hardness, and corrosion resistance, improve the grade of products. At the same time, the products with finished product appearance, and durable, scrap rate low characteristic.
Second, metallurgical industry: in metallurgical and foundry sand adding spodumene to eliminate casting veining defect, reduce or eliminate casting thermal expansion defects, defects of gas, and the role of anti sticking sand; after adding spodumene in continuous casting protecting slag to reduce the melting temperature of the slag, reduce the high temperature viscosity, lubrication condition optimization, can inhibit the casting under the high temperature oxidation, carbonization.
After three, refractory industry: in refractory material adding spodumene can reduce the sintering temperature, so it is refractory industry preferred sintering mineralizer; refractories mechanical strength, thermal shock resistance and volume stability can be improved; can enhance the refractory corrosion resistance of high temperature, prolong the service life of the refractory; widely used in Mo mullite, cordierite shed plate, crucible, sagger, heat plate temperature refractories and refractory castable, plastics, mending material, spray coating, adhesive, paint and other unshaped refractory materials.
