    Abstract：The R2O-RO-Al2O3-B2O3-SiO2 low-temperature and high-strength frit glaze was prepared by orthogonal experiment. The influence of each oxide on the properties of glaze was investigated. Study the melting temperature of the glaze formula，the flexural strength，Vickers hardness，phase composition and crystal structure. The results show that the formation of CaSiO3 in the glaze block has a positive effect on the properties of the glaze block. The optimum flexural strength is up to 76.03 MPa and the optimum glaze Vickers hardness is up to 7208 MPa.
