Abstract

The invention relates to the technical field of glass processing, in particular to a crystal phase regulator and a microcrystalline glass using the same. The crystal phase regulator is a novel compound additive, and is used for clarifying and tempering the melting liquid of the microcrystalline glass, improving the crystallizing property of the melting body in the crystallizing process, and increasing the crystallizing rate of the microcrystalline glass to 75% or above. A formula of the microcrystalline glass using the crystal phase regulator comprises the following components of 16 to 20% ofmagnesium oxide, 15 to 19% of aluminum oxide, 0.5 to 0.8% of titanium dioxide, 1.3 to 2.2% of boron oxide, 12 to 14.5% of crystal phase regulator, and the balance of silicon dioxide and unavoidable impurities. By adopting the technical scheme, the microcrystalline glass has the advantages that the mechanical strength is high, the high temperature-resistant property is realized, and the easiness inself explosion is avoided; the qualified rate in production is increased, and the production cost is reduced.
