Description
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: 50%≤silicon-dioxide < 56%, 0≤aluminum oxide < 1%, 18% < calcium oxide≤25%, 1%≤boron oxide≤2%, 5%≤potassium oxide <, 8%, 0 < zinc oxide≤4%, 2% < fluorine≤5%, surplus is sodium oxide.
Each composition at jade shape devitrified glass provided by the invention limits as follows by weight percentage:
Silicon-dioxide is given the chemical stability that devitrified glass is good, thermostability, the transparency, higher softening temperature, hardness and physical strength, but along with content increases, melt temperature raises, glass metal viscosity increases, and be difficult to form devitrified glass, so the content of silicon-dioxide is set as: 50%≤silicon-dioxide < 56%.
Aluminum oxide can reduce the tendency towards devitrification of devitrified glass, improve chemical stability and physical strength, improve thermostability, but the lifting along with alumina content, can improve the viscosity of glass metal, make fusing and clarification that difficulty occur, increase on the contrary tendency towards devitrification, so the content of aluminum oxide is set as: 0≤aluminum oxide < 1%.
Calcium oxide can reduce the high-temperature viscosity of glass metal, promotes fusing and the clarification of glass metal, increase chemical stability and the physical strength of devitrified glass, so the content of calcium oxide is set as: 18% < calcium oxide≤25%.
Boron oxide can reduce the thermal expansivity of devitrified glass, improves thermostability, and the processability of improving devitrified glass, so the content of boron oxide is set as: 1%≤boron oxide≤2%.
Potassium oxide is good solubility promoter, can reduce the viscosity of glass metal, promotes fusing and the clarification of glass metal, can also greatly reduce the tendency towards devitrification of devitrified glass, so the content of potassium oxide is set as: 5%≤potassium oxide < 8%.
The viscosity of glass metal when zinc oxide can reduce high temperature, improve chemical stability and the specific refractory power of devitrified glass, but along with the increase of zinc oxide content, can cause the thermal expansivity of devitrified glass to increase, so the content of zinc oxide is set as: 0 < zinc oxide≤4%.
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%.
Sodium oxide can reduce the viscosity of glass metal, promote fusing and the clarification of glass metal, so the remaining composition of devitrified glass is set as sodium oxide.
Jade shape devitrified glass of the present invention is not introduced the magnesium oxide that can improve annealing temperature, the composition proportion of the low aluminium high calcium of its low 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.
