Technical Field

Background
The luminous glaze can still continuously emit light after an external light source is removed. At present, the luminescent ceramics are produced industrially by mainly using luminescent glaze which takes metal sulfide or rare earth doped aluminate as a substrate and sintering at a low and medium temperature. But the environmental adaptability is poor, the use condition is harsh, and the low-temperature sintered rare earth doped silicate luminescent ceramic product meets the requirements of the industry and has larger market space for the characteristics of different luminescent glazes. The long-afterglow luminous glaze consists of luminous powder, base glaze, additive and other components. When the luminescent ceramic glaze is synthesized by a microwave method by selecting the medium-low temperature base glaze frits suitable for the silicate long afterglow luminescent color, the higher the microwave sintering temperature is, the longer the microwave heat preservation time is, the more seriously the long afterglow luminescent material is damaged by high temperature melting, and when the content of the long afterglow luminescent powder is too low, the luminescent powder density in the luminescent ceramic glaze is low, so that the luminescent performance of the luminescent ceramic glaze is poor. When the content of the long-afterglow luminescent powder is too high, the glaze surface is rough and bubbles appear, so that the quality of the luminescent ceramic glaze surface is poor.
