Inventor

Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon;zar-gun, "gold-like" or "as gold")), the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion. Zirconium forms a variety of inorganic and organometallic compounds such as zirconium dioxide and zirconocene dichloride, respectively. Five isotopes occur naturally, three of which are stable. Zirconium compounds have no known biological role.

Matte glaze and preparation method thereof

The invention discloses a matte glaze and a preparation method thereof. The matte glaze comprises the following components by weight: 1-5 parts of zinc oxide, 5-15 parts of barium carbonate, 0-15 parts of zirconium silicate, 10-25 parts of potassium feldspar, 10-20 parts of kaolin, 5-15 parts of calcite, 5-15 parts of calcined talcum powder, 20-35 parts of a matte frit and 0.5-1 part of an additive. Specifically, the matte frit comprises the following components by weight: 30-50 parts of SiO2, 15-20 parts of Al2O3, 0.01-0.5 part of Fe2O3, 3-10 parts of CaO, 0.5-5 parts of MgO, 1-5 parts of K2O, 3-10 parts of Na2O, 3-10 parts of ZnO, 0.1-1 part of B2O3 and 10-25 parts of BaO. By introducing the matte frit, the melting temperature of the formula is lowered, the firing range of the formula isbroadened, and the glaze texture achieves a fine matte effect.
