1 results about "Frit" patented technology

A frit is a ceramic composition that has been fused, quenched, and granulated. Frits form an important part of the batches used in compounding enamels and ceramic glazes; the purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by causing them to combine with silica and other added oxides. However, not all glass that is fused and quenched in water is frit, as this method of cooling down very hot glass is also widely used in glass manufacture.

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.
