Quality China Fire Assay Crucible Manufacture And Factory Magnesia Cupel for Melting Gold Manufacturer | XTL

6A 7A 8A China Fire Assay Crucible Manufacture And Factory Magnesia Cupel for Melting Gold compared with similar products on the market, it has incomparable outstanding advantages in terms of performance, quality, appearance, etc., and enjoys a good reputation in the market. Xngtailong summarizes the defects of past products and continuously improves them. The specifications of 6A 7A 8A China Fire Assay Crucible Manufacture And Factory Magnesia Cupel for Melting Gold can be customized according to your needs.Cupel is a porous refractory for absorbing lead oxide when ash blows the lead buckle. The main component of magnesia is magnesium oxide, which is a very good refractory and can resist the erosion of alkaline flux. Lead oxide is a very strong alkaline flux. At high temperatures, the affinity between lead oxide and silica is very strong, which can invade the silicate in the cupel. There is more silicate in the ash cupel and cement cupel. After blowing with this kind of cupel, there will be pits on the surface of the cupel, and precious metals will be lost as a result. Using magnesia cupel, no such phenomenon after ash blowing, the surface is very smooth.
