Abstract

The invention discloses a pore-free sinter molding microcrystal jade and a manufacturing technology, and belongs to the technical field of glass ceramics. The pore-free sinter molding microcrystal jade is characterized by comprising raw mineral materials occupying 75-85% of the total weight and auxiliary chemical raw materials occupying 15-25% of the total weight. The raw mineral materials are quartz sand, calcite, potassium feldspar, fluor, dolomite; and the auxiliary chemical raw materials are aluminum oxide, sodium carbonate, potassium carbonate, sodium nitrate, and zinc white. The production technology of the sinter molding microcrystal jade comprises high-temperature leveling, low-temperature nucleation and devitrification. The sinter molding microcrystal jade section has a texture of a natural jade, the surface and section are pore-free and take transparent and semitransparent jade shapes. The sinter molding microcrystal jade has the moist degree and waxy texture of the natural jade, has high toughness and excellent strength.

Description

technical field [0001] A non-porous sintered microcrystalline jade and its production process belong to the technical field of microcrystalline jade, and relate to a microcrystalline jade and a production process through a sintering method. Background technique [0002] Microcrystalline jade is also called glass-ceramic or glass-ceramic. It is a new type of building material. It has the dual characteristics of glass and ceramics. The atomic arrangement inside ordinary glass is irregular, which is one of the reasons why glass is fragile. Microcrystalline jade is composed of crystals, and the arrangement of atoms is regular. Therefore, microcrystalline jade is brighter than ceramics and tougher than glass. [0003] The following are two traditional methods of producing microcrystalline jade: [0004] 1. Microcrystalline jade is fired by granular method: this microcrystalline jade is CaO-Al 2 o 3 -SiO 2 The series of microcrystalline jade are mostly microcrystalline jade...
