The jade-like microcrystalline glass looks like semitransparent jade; possesses smooth feel and wax feel of natural jade; is high in toughness and strength; is convenient for further machine shaping; and can be widely used in the fields of substitute goods of high-grade stone.

Description

A kind of jade shape devitrified glass
Technical field
The present invention relates to glass-ceramic field, particularly a kind of jade shape devitrified glass.
Background technology
Along with Chinese national economy is stablized sustainable development, people's living standard improves thereupon, demand expanding day to high-grade material, particularly more urgent to the substitute products demand of radiationless high-grade stone material, but the substitute products fragility of domestic high-grade stone material is large, be not easy machine-shaping, cause a lot of high-grade stone materials need to be from external import, cost greatly promotes.
Devitrified glass is called again glass-ceramic, has glass and ceramic dual nature, and devitrified glass is by crystal composition, and its atomic arrangement is regular, and therefore, devitrified glass is higher than ceramic brightness, and stronger than glass toughness.Devitrified glass has been concentrated triple advantages of glass, pottery and lithotome, be better than lithotome and pottery, can be used for building curtain wall and indoor high-grade decoration, also can do structured material mechanically, insulating material on electronics, electrician, the baseboard material of large-scale integrated circuit, the heat-resisting row vessel of microwave oven, chemical industry and impregnating material and mine high-abrasive material etc., become the substitute products of desirable high-grade stone material.
Existing devitrified glass exist tone single, there is no texture, apparent porosity is high and fragility is large, is not easy the shortcomings such as machine-shaping, causes devitrified glass to utilize space little, share of market is low, severe inhibition the development of devitrified glass industry.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of good toughness, jade shape devitrified glass that intensity is high.
For solving the problems of the technologies described above, jade shape devitrified glass provided by the invention comprises following composition by weight percentage: 56% < silicon-dioxide≤65%, 12% < sodium oxide≤15%, 8% < potassium oxide≤10%, 18% < calcium oxide≤20%, 2% < fluorine≤5%, surplus is aluminum oxide.
Each composition at jade shape devitrified glass provided by the invention limits as follows by weight percentage:
Silicon-dioxide is given chemical stability and the thermostability that devitrified glass is good, can improve the intensity of devitrified glass, reduce the coefficient of expansion of devitrified glass, but along with content increases, can cause the viscosity of glass metal to increase, the glass melting temperature of devitrified glass raises, so the content of silicon-dioxide is set as: 56% < silicon-dioxide≤65%.
Sodium oxide can reduce the viscosity of glass metal, promote fusing and the clarification of glass metal, so the content of sodium oxide is set as: 12% < sodium oxide≤15%.
Potassium oxide is good solubility promoter, can improve the glossiness of devitrified glass, promotes fusing and the clarification of glass metal, can also reduce the viscosity of glass metal, so the content of potassium oxide is set as: 8% < potassium oxide≤10%.
Calcium oxide can reduce the high temperature viscosity of glass metal, promotes fusing and the clarification of glass metal, increase chemical stability, physical strength and the hardness of devitrified glass, so the content of calcium oxide is set as: 18% < calcium oxide≤20%.
Fluorine is a kind of good opacifying agent, and during fluorine too high levels, the chemical stability of devitrified glass reduces, easy devitrification, so the content of fluorine is set as: 2% < fluorine≤5%.
Aluminum oxide can reduce the tendency towards devitrification of devitrified glass, improves chemical stability and physical strength and hardness, improves thermostability, reduce electrical insulating property, so the remaining composition of devitrified glass is set as aluminum oxide.
The jade shape devitrified glass of the present invention zinc oxide that introducing can not improve the magnesium oxide of annealing temperature and can cause thermal expansivity to increase, and easily cause holding volatile Vanadium Pentoxide in FLAKES in product aberration and use, the composition proportion of the high sodium high calcium of its high silicon can effectively reduce the apparent porosity of jade shape devitrified glass, improve impelling strength and anti-folding, ultimate compression strength, strengthen machine-shaping property, the perception of this jade shape devitrified glass presents translucent beautiful matter shape, has moist degree and the wax sense of natural jade.
Preferably, the main crystalline phase of described jade shape devitrified glass is Na 4~3k 2~3ca 5(Si 12o 30) F 4, this crystalline phase is lath-shaped, has greatly improved toughness and the bending and compressive strength of jade shape devitrified glass, and is easy to processing cutting.
Preferably, the impelling strength of described jade shape devitrified glass is 5.0kj/cm 3~5.6kj/cm 3.
Preferably, the Mohs' hardness of described jade shape devitrified glass is 6.5~7.5.
Preferably, the folding strength of described jade shape devitrified glass is 65MPa~80MPa.
Preferably, the ultimate compression strength of described jade shape devitrified glass is 600MPa~800MPa.
Preferably, the visible light transmissivity of described jade shape devitrified glass is 30%~40%.
Jade shape devitrified glass perception provided by the invention presents translucent beautiful matter shape, has moist degree and the wax sense of natural jade, and good toughness, intensity are high, and easily further machine-shaping can be widely used in the fields such as substitute of high-grade stone material.
Embodiment
