Abstract

The invention relates to an oral cavity bio-active nucleated glass with adjustable colour and its rpeparation method. Its preparation method includes the following steps: firstly, uniformly mixing raw materials according to a certain mixing ratio, melting for 3 hr. at 1400-1550 deg.C, pouring the molten glass inti mould and forming to obtain blank, cooling to room temp., heating glass blank and heat-insulating to make glass nucleate, continuously heating and heat-insulating to make glass crystallize to obtain the bio-active nucteated glass using apatite and fluorophlogopite as main crystal phase. Said nucleated glass uses TiO2/ZrO2 as crystal nucleus agent, and contains a certain crystal phase formed from leucite and calc-silicate stone to raise its strength, and said product possesses good bio-compatibility, machinability and beautifulness.

Description

Oral cavity bioactive devitrified glass that a kind of color and luster is adjustable and preparation method thereof
