Problems solved by technology

[0003] In the process of ceramic preparation, frit is the main material for making low glaze. The frit in the prior art is mostly added with a large amount of heavy metal lead, which brings great toxic hazards to users and producers, and the existing The color distribution of the glaze surface prepared by the frit is not uniform. As people's environmental protection seems to be strengthened, it is necessary to develop and design a lead-free milky white frit that is environmentally safe and uniform in color based on the existing technology.

Abstract

The invention discloses lead-free opalescent frit for ceramics preparation, which is prepared from the following raw materials in part by weight: 50-60 parts of SiO2, 5-10 parts of Al2O3, 5-10 parts of CaO, 5-10 parts of ZnO, 10-20 parts of B2O3, 10-20 parts of ZrO2 and 5-10 parts of alkali metal. The lead-free opalescent frit for ceramics preparation disclosed by the invention has the advantages of no added poisonous lead element, environment friendliness, safety, uniform opalescence and wide application scope.

Description

[0001] technical field [0002] The invention relates to a frit for preparing ceramics, in particular to a lead-free opalescent frit for ceramics. Background technique [0003] In the process of ceramic preparation, frit is the main material for making low glaze. The frit in the prior art is mostly added with a large amount of heavy metal lead, which brings great toxic hazards to users and producers, and the existing The color distribution of the glaze surface prepared by the frit is not uniform. As people seem to strengthen their awareness of environmental protection, it is necessary to develop and design a lead-free milky white frit that is environmentally safe and uniform in color based on the existing technology. Contents of the invention [0004] Purpose of the invention: The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a lead-free milky white frit that does not add metal lead, is safe and environ...
