The invention discloses a lead-free transparent frit for ceramic preparation.

The lead-free transparent frit for ceramic preparation is made of, by weight, 60 parts of SiO2, 20 parts of Al2O3, 5 parts of MgO, 30 parts of CaO and 20 parts of K2CO3. The optimal composition and proportion are determined by screening from a great amount of tests according to the property requirements of the lead-free transparent frit.

Test results show that the lead-free transparent frit for ceramic preparation is scientific and reasonable in component proportion, and ceramic products prepared by the lead-free transparent frit are fine in glaze smoothness, excellent in enamel, especially transparent and bright, free of lead, environment-friendly and wide in application range.
