Description
Technical field
The present invention relates to glass-ceramic field, particularly to a kind of low-fluorine microcrystalline glass.
Background technology
Along with Chinese national economy stablizes sustainable development, people's living standard improves therewith, builds top grade
The demand expanding day of material, particularly the most urgent to the substitute products demand of radiationless high-grade stone,
But the substitute products fragility of domestic high-grade stone is big, it is not easy to machine-shaping, cause a lot of high-grade stone
Material needs from external import, and cost significantly increases.
Devitrified glass is also called glass-ceramic, have glass and pottery double grading, devitrified glass by
Crystal forms, and its atomic arrangement is regular, and therefore, devitrified glass is higher than the brightness of pottery, and ratio
Glass toughness is strong.Triple advantages of glass, pottery and lithotome concentrated by devitrified glass, are better than sky
So stone material and pottery, can be used for building curtain wall and indoor high-grade decoration, also can do structural wood mechanically
Material, the insulant on electronics, electrician, the baseboard material of large scale integrated circuit, microwave oven are heat-resisting
Split vessel, chemical industry and anti-corrosion material and mine high-abrasive material etc., become the replacement of preferable high-grade stone
Product.
Existing devitrified glass mostly is high fluorine glass product, volatilizees aborning due to fluorine serious, makes raw
The bad control of stability produced, causes devitrified glass to produce success rate relatively low, even if successfully producing micro-
Crystal glass there is also that tone is single, do not have that texture, apparent porosity are high, production stability is low and crisp
Property big, it is not easy to shortcomings such as machine-shaping, and high fluorine glass product is rotten to kiln in process of production
Erosion is serious, causes kiln shortening in service life, and production cost increases.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of exquisite in texture, glittering and translucent, good toughness,
The low-fluorine microcrystalline glass that intensity is high.
For solving above-mentioned technical problem, the low-fluorine microcrystalline glass that the present invention provides is wrapped by weight percentage
Include following composition: 72% ＜ silicon dioxide≤75%, 8% ＜ potassium oxide≤12%, 13%≤calcium oxide ＜
18%, 1%≤fluorine≤3%, 0≤aluminium oxide ＜ 1%, 0 ＜ zinc oxide≤4%, 0 ＜ titanium oxide≤2%,
Surplus is sodium oxide.
The most defined below at each composition of the devitrified glass of present invention offer:
Silicon dioxide gives the good chemical stability of devitrified glass and heat stability, can improve crystallite glass
The intensity of glass, reduces the coefficient of expansion of devitrified glass, but along with content increases, can cause vitreous humour
Viscosity increases, and the glass melting temperature of devitrified glass raises, and therefore the content of silicon dioxide is set as: 72%
＜ silicon dioxide≤75%.
Potassium oxide is good cosolvent, can improve the glossiness of devitrified glass, promotes the molten of vitreous humour
Change and clarification, moreover it is possible to reducing the viscosity of vitreous humour, therefore the content of potassium oxide is set as: 8% ＜ oxidation
Potassium≤12%.
Calcium oxide can reduce the high temperature viscosity of vitreous humour, promotes fusing and the clarification of vitreous humour, increases micro-
The chemical stability of crystal glass, mechanical strength and hardness, therefore the content of calcium oxide is set as: 13%
≤ calcium oxide ＜ 18%.
Fluorine is a kind of excellent opacifiers, and when Oil repellent is too high, the production stability of devitrified glass is low, crisp
Property big, easy devitrification, therefore the content of fluorine is set as: 1%≤fluorine≤3%, it is highly preferred that 1%≤fluorine
＜ 2%.
Aluminium oxide can reduce the tendency towards devitrification of devitrified glass, improve chemical stability and mechanical strength and
Hardness, improves heat stability, reduces electrical insulating property, but along with the lifting of alumina content, can cause
Devitrified glass surface generation striped, and the viscosity of vitreous humour can be improved, make fusing and clarification that difficulty to occur,
Increasing tendency towards devitrification on the contrary, therefore the content of aluminium oxide is set as: 0≤aluminium oxide ＜ 1%.
Zinc oxide can improve the chemical stability of devitrified glass, reduces the thermal coefficient of expansion of devitrified glass,
But along with the increase of zinc oxide content, ceramics tendency, the therefore content of zinc oxide can be increased
It is set as: 0 ＜ zinc oxide≤4%.
Titanium oxide can reduce the thermal coefficient of expansion of devitrified glass, but when introducing too much, can increase crystallite glass
The crystallize ability of glass, therefore the content of titanium oxide is set as: 0 ＜ titanium oxide≤2%.
Sodium oxide can reduce the viscosity of vitreous humour, promotes fusing and clarification, the therefore crystallite glass of vitreous humour
The remaining composition of glass is set as sodium oxide.
In low-fluorine microcrystalline glass of the present invention, Oil repellent is low, and the composition proportion of its low fluorine high-silicon high potassium is conducive to
Improve stability and success rate, the low-fluorine microcrystalline glass surface of mentioned component proportioning that devitrified glass produces
The porosity is low, and water absorption rate is low, impact flexibility and anti-folding, comprcssive strength height, and machine-shaping property is strong,
The perception of this low-fluorine microcrystalline glass presents translucent beautiful matter shape, and exquisite in texture is glittering and translucent.
Preferably, the principal crystalline phase of described low-fluorine microcrystalline glass is Na4～3K2～3Ca5(Si12O30)F4, this
Kind of crystalline phase is lath-shaped, substantially increases toughness and the bending and compressive strength of low-fluorine microcrystalline glass, and easily
In processing cutting.
Preferably, the impact flexibility of described low-fluorine microcrystalline glass is 5.0kj/cm3～5.6kj/cm3。
Preferably, the Mohs' hardness of described low-fluorine microcrystalline glass is 6.0～7.0.
