Description
Technical field
The present invention relates to glass making techniques fields, and in particular to a kind of novel nucleated glass and preparation method thereof.
Background technology
As Chinese national economy stablizes sustainable development, people's living standard improves therewith, the demand day to high-grade material
Benefit expands, especially more urgent to the substitute products demand of radiationless high-grade stone, but the replacement production of domestic high-grade stone
Product brittleness is big, it is not easy to which machine-shaping causes many high-grade stones to need from external import, and cost significantly increases.
Devitrified glass is also known as glass-ceramic, and the double grading with glass and ceramics, devitrified glass is made of crystal,
Atomic arrangement is regular, and therefore, devitrified glass is higher and stronger than glass toughness than the brightness of ceramics.Devitrified glass has concentrated glass
Triple advantages of glass, ceramics and lithotome are better than lithotome and ceramics, can be used for building curtain wall and indoor high-grade decoration,
Structural material mechanically, the insulating materials on electronics, electrician, baseboard material, the micro-wave oven of large scale integrated circuit can also be done
The vessel of resistance to hot tearing, chemical industry and anti-corrosion material and mine wear-resistant material etc. become the substitute products of ideal high-grade stone.
Existing devitrified glass is mostly high fluorine glass product, since fluorine volatilizees seriously in production, makes the stability of production
Bad control causes devitrified glass production success rate relatively low, even if successfully produce devitrified glass there is also tones it is single, do not have
It is textured, apparent porosity is high, production stability is low and brittleness is big, it is not easy to the shortcomings of machine-shaping, and high fluorine glass produces
Product to kiln seriously corroded, cause kiln reduced service life, production cost to increase in process of production.
Therefore, it is particularly important to develop a kind of novel nucleated glass.

A kind of novel nucleated glass of present invention offer and preparation method thereof, advantage is compared with prior art：
Whisker is uniformly dispersed in the glass matrix of novel nucleated glass of the present invention, and whisker is well combined with glass matrix, carries
The high mechanical property of devitrified glass, novel nucleated glass fluorine content of the present invention is low, which is presented translucent jade
Matter shape, the moisture with natural jade and wax sense, exquisite in texture is glittering and translucent, radiationless, and good toughness, intensity are high,
It is easy further processing molding, can be widely used in the fields such as the substitute of high-grade stone；
Novel nucleated glass preparation process of the present invention is simple, and nucleating agent can be effectively facilitated silica, oxidation in raw material
Calcium, aluminium powder, magnesia start crystallization at a lower temperature, and are formed using diopside as the devitrified glass of principal crystalline phase；Control is former
Expect composition proportion, it is therefore an objective to control crystallization amount, keep glass glossy, improve the brightness value of glass, silica, zircon,
The effect of whisker, silica sand, aluminium powder forms glass network, simultaneously participates in the formation of principal crystalline phase as Network former.It improves micro-
The chemical stability of crystal glass.Calcium oxide, magnesia, potassium oxide are as network modifying oxide, except reduction glass system
Outside glass melting temperature, breakpoint effect is also acted as, is conducive to the precipitation of crystal.Nucleating agent promotion system is nucleated crystallization, and zirconium dioxide is made
Contribute to crystal grain thinning for Nucleating Agent, keeps crystal grain more uniform, it is beneficial for the raising of mechanical strength, but excessively can also increase
Fusion temperature, and then improve the performance of glass.
