Abstract

An emerald microcrystalline glass comprises base glass and Cr2O3, and a weight ratio of the Cr2O3 to the base glass is 0.01-0.2%; and the base glass comprises 70-80 wt% of SiO2, 12-15 wt% of Na2O, 8-10 wt% of CaO, 1.0-3.8 wt% of MgO, 0.2-1.8 wt% of Al2O3 and 0-0.5 wt% of K2O. The emerald microcrystalline glass has the advantages of fine, soft and moist qualitative sense, and excellent cutting ability, and can be engraved.

Description

technical field [0001] The invention relates to a glass-ceramic and a preparation method thereof, in particular to an emerald-colored glass-ceramic and a preparation method thereof, belonging to the technical field of glass ceramics. Background technique [0002] At present, glass-ceramics used as decorative materials are mostly produced by bead sintering method, and their crystal structure is mainly wollastonite phase. The disadvantages of this glass-ceramic are: [0003] (1) The grain size of the wollastonite phase in the material is large, and the color does not have a delicate and soft texture; [0004] (2) The material is brittle and difficult to process and use. In addition, there are some milky white or black glasses produced by rolling method and float method at present. They belong to the category of milky glass, in which the crystal phase accounts for a small proportion and the glass phase is more, which is easy to be cut in the cutting process. There are phenom...
