Zusammenfassung:The invention relates to a microcrystalline glass seeding agent, which comprises the following main chemical components by weight percentage: 65-79% of SiO2, 3.5-6.5% of Al2O3, 10-15.5% of B2O3, 0-2% of CaO, 0-2% of MgO, 5-10% of BaO+ZnO, 2.5-6.5% of K2O+Na2O. The microcrystalline glass seeding agent has little viscosity and little surface tension, decoration aesthetics of the microcrystalline glass is increased, and large spangles are formed on the surface of the microcrystalline glass. The invention also provides a preparation technology of the seeding agent, the method is simple, the technology controllability is strong, the obtained product has stable and uniform property, and is suitable for large scale production.
