Product Description
DIOPSIDE
Introduction:
Diopside is a common kind of pyroxene, it belongs to the silicate mineral, is the calcium and magnesium silicate.The chemical formula is CaMg (SiO3) 2, the chemical composition of diopside (Wb %) : CaO is 25.9%, MgO is 18.5%, SiO2 is 55.6%.The secondary component Al2O3 is generally 1~3% and can be as high as 8%.Al3+ can replace Mg2+ and Fe2+, and can also replace Si. If Si is replaced by more than 7%, it is called aluminum diopside.Rich in Cr2O3 is called chromium-diopside, which is one of the characteristic minerals of kimberlite.

1.Ceramic industry
Nowadays, ceramic industry tends to low temperature quick firing, diopside has its unique effect in low temperature quick firing.In the process of heating up, diopside has no crystal transformation, no burning loss, good thermal expansion property, can quickly promote the sintering of the billet body, and plays a role of strong mineralizer.Diopside can realize the low temperature quick firing of ceramics, improve the performance of ceramics, widely used in electric ceramics, building ceramics and daily ceramics industry, is a good new energy-saving additive and ceramic raw materials.In the building ceramics industry, the comprehensive properties of diopside are better than wollastonite.For high-frequency porcelain, diopside porcelain is superior to talc.
2.Glass raw material
The low soda soda daily glass made from diopside, tremolite and potash feldspar was melted at temperatures of 1360~1370ºC. The products have higher upper limit temperatures of softening, annealing and crystallization, and have good thermal stability, chemical stability and mechanical strength.
3.Metallurgical protective slag
Metallurgical protective slag prepared with diopside, potassium feldspar or transblende and potassium feldspar as the base material can protect molten steel from oxidation in the process of casting ingot, which has good effect on improving the surface finish of ingot and reducing the loss of peeling.
4.electrode
Analysis of the current type of electrode is divided into chin-type, chin-calcium type, chin-acid type, alkali type, etc., the above various types of electrode contain CaO, and SiO2 components, so diopside can be used in all the electrode.The chemical composition of diopside is suitable for all the slag system of the electrode. This kind of radial silicate can improve the pressure coating performance of the electrode, and because of the large amount of CaO and MgO, whether in alkaline or acid electrode, it has the effect of improving the low temperature impact toughness of the deposited metal and improving the mechanical properties of the deposited metal.
