Abstract
The invention belongs to the field of medical materials, especially to leucite microcrystalline glass and its preparation method and application. The method comprises the following steps: firstly calcining raw materials such as SiO2, Al2O3, K2O, B2O3, etc. for the first time to obtain leucite baked porcelain blocks, crushing, ball-milling by a wet method, drying and sieving to obtain leucite baked porcelain powder, tabletting the above prepared leucite baked porcelain powder and calcining so as to prepare the leucite microcrystalline glass. Grain size of leucite crystal grains in the leucite baked porcelain powder is about 1 micron. By small grain size, strength of the leucite microcrystalline glass can be effectively raised. After tabletting and calcining, the leucite microcrystalline glass has high strength and good transmittance. The invention provides a new method for preparation of the leucite microcrystalline glass.
Description
Technical field
The invention belongs to field of medical materials, particularly to a kind of leucite devitrified glass, its preparation method and should
With.
Background technology
Microcrystal glass material is just with its good biocompatibility since being applied to clinic, and extremely strong is anti-corrosion
Property and close to the advantage such as color and luster of natural teeth, become the main material being applied to treat injury of teeth.Its
Middle leucite devitrified glass has obtained extensively with its high thermal coefficient of expansion, good mechanical performance and biological property
General application.Leucite (K2O-Al2O3-4SiO2) as K2O-Al2O3-SiO2The master of system glass ceramics
Phase, Dispersed precipitate, in glass basis, directly affects the performance of matrix, has been applied to external some dentistry pottery
To improve the mechanical strength of dummy and to beautify the color and luster of dummy in porcelain products.China All-ceramic Dental Material master
Rely on external import, but owing to import All-ceramic material is expensive, greatly limit it and face
Bed application, reason is that the microcrystal glass material of domestic production is at mechanical property, thermal coefficient of expansion, color and luster etc.
Aspect is unable to reach the standard of imported material.Therefore independent research domestic dentistry microcrystal glass material is to reduce into
Originally there is important practical significance.
Leucite (K2O-Al2O3-4SiO2) as K2O-Al2O3-SiO2The principal phase of system glass ceramics, more
Dissipate and be distributed in glass basis, directly affect the performance of matrix.Tradition prepare the method for leucite have solid phase method,
Hydro-thermal method, sol-gal process, coprecipitation etc., wherein solid phase method prepares leucite devitrified glass is to use
Water quenching prepares pristine glass, then carries out crystallization crystalline substance process in sintering process, compared to additive method, Gu
Phase method have simple to operate controlled, the cycle is short, low cost and other advantages.
There is big, the highest, the leucite crystal skewness of obdurability of fragility etc. in domestic leucite devitrified glass
Shortcoming.Therefore, it is necessary to drug formulation reasonable in design, and improve by improving system of heat treatment process
Himself shortcoming so that it is intensity, fragility, light transmission and material homogeneity meet Clinical practice requirement.White pomegranate
Stone devitrified glass is currently mainly prepared through Overheating Treatment crystallize by pristine glass, will pharmaceutical raw material mixing add
Heat is melted, and shrend prepares pristine glass, and pristine glass is carried out heat treatment, makes crystal separate out and prepares leucite
Devitrified glass.Pristine glass is generally by SiO2、Al2O3、K2O、Na2O、B2O3、TiO2Form etc. component,
Wherein SiO2、Al2O3And K2O is the main body of glass composition, is mainly used to separate out leucite crystal, Na2O
It is mainly used in reducing pristine glass fusing point, TiO2As nucleating agent.
CN 1442380 A discloses a kind of dentistry devitrified glass, including the K of 15-25%2O, 20-30%'s
Al2O3, the SiO of 50-60%2, the Fe of MgO, 0.04-001% of CaO, 0.1-0.8% of 1-6%2O3With
0.04-0.1%TiO2's.The dentistry devitrified glass of this application has the physicochemical property of excellence, but preferable not enough.
Even if it should be noted that in a lot of patent and all comprising SiO2、Al2O3、K2O、Na2O and B2O3
Etc. component, but the trickleest change of these components may result in leucite devitrified glass performance and produces the biggest
Change.Griffith micro-crack theory is pointed out, present in material, micro-crack is under the effect of external force, meeting around
Generation stress is concentrated, and when stress reaches certain degree, crackle will extend until rupturing.Devitrified glass
Mechanical property strengthen mechanism, be widely considered to be due to leucite Dispersed precipitate in glass mutually in, in glass produce
Raw crackle will be hindered by leucite crystal when extension, and leucite separates out the most, and this obstruction is just
Can be more strong so that the intensity of devitrified glass has increased.The generally size of dialogue garnet crystal needs
Strictly control, typically require that it is smaller in size than 4 μm, so can be effectively prevented from devitrified glass
Stress is concentrated.
Devitrified glass is a kind of translucent goods, and its light transmission directly affects the attractive in appearance of tooth, by transmittance
Index may determine that the uniformity that crystal in sample separates out.Measuring the matter identifying devitrified glass of transmittance
Measurer has important practical significance.The thickness of material directly affects its optical property, the amount of crystal in material,
The uniformity of chemical characteristic, the granular size of crystal and crystal grain distribution determines the light transmission of material.
