Description
Technical field
The invention belongs to technical field of ceramic material, and in particular to a kind of glass ceramics and preparation method thereof.
Background technique
Ceramic material is natural or synthetic compound through one kind inorganic non-metallic material made of overmolding and high-temperature calcination,
Ceramic material can be divided into two major classes according to its performance and purposes：Structural ceramics and function ceramics, function ceramics, which refers to, to be applied
When mainly utilize the material of its non-mechanical property, this material usually has one or more functions.Such as electricity, magnetic, light, heat, change
The functions such as, biology, function ceramics is many kinds of, and purposes is different.
Glass ceramics (i.e. devitrified glass) has the double grading of glass and ceramics, and the atomic arrangement inside simple glass is
Do not have one of the reason of well-regulated, this is also Glass breadks easily.And glass ceramics is made of as ceramics crystal, that is to say, that
Its atomic arrangement is regular.So glass ceramics is higher than the brightness of ceramics, it is stronger than glass toughness.Glass ceramics, also known as
Devitrified glass, traditional glass ceramics manufacturing method are a kind of crystal phase obtained by high temperature melting, molding and heat treatment and glass
The composite material that glass combines.Glass ceramics has high mechanical strength, and hot expansibility is adjustable, heat shock resistance, resistant to chemical etching,
The superior performance such as low-dielectric loss.In biomedicine field, bioceramic is often used in manufacture dental material, artificial bone
Joint and the filler of bone bonding agent etc..
The method of manufacture glass ceramics generally includes three key steps：Raw material is melted first, such as raw material
Mixture is usually melted at 1500~1700 DEG C；Again by the cooling acquisition melten glass of the slurry of melting and punch forming；Most
Crystallization or ceramic are carried out by suitable heat treatment (including nucleation and crystal growth phase) glass cooling to molding afterwards.
High temperature resistant glass ceramic is the application with new processes such as sintering process, sol-gel methods in glass ceramics preparation
And the new material to grow up.When precipitation such as mullite, spinelle, pollucite crystal resistant to high temperature and content in glass ceramics
When higher, material can be with resistance to very high temperature.In pollucite glass ceramics, this high temperature resistant crystallite is not only precipitated, has also analysed
Some mullite crystals are gone out, and its residual glass phase is wrapped up by crystal, this material can be in 1400 DEG C or so of high temperature
Lower use.
The microstructure of the material glass ceramics of strong mechanical performance has a significant impact to its mechanical property, can use control structure
Improve performance, as intensity and toughness can be improved in pilotaxitic texture；Keep crystal orientation raw using the methods of temperature gradient, hot extrusion
Length can also increase substantially mechanical property, such as with CaO-P2O5For orientation crystallite, flexural strength are precipitated in the glass ceramics of base
Up to 700MPa, and fracture toughness also significantly improves；Composite material is the another effective way for improving glass ceramics mechanical property
Diameter can will have compound therewith different from the fiber of glass-ceramic substrate mechanical property, whisker or particle, it is also possible to metal etc. its
Its material is compound therewith, and the fiber of glass ceramics or spherula can also be combined in other matrixes, such as uses SiC whisker reinforcement
MgO-Al2O3-SiO2The glass ceramics of base, flexural strength and fracture toughness are respectively 500MPa and 4.0MPa, than non-reinforced person
Improve twice or more.The mechanical property of composite material can be with Si3N waits structural ceramics to match in excellence or beauty, and is a kind of promising new structure
Material.
The major advantage of biological glass ceramic biological glass ceramic is can to introduce CaO, P in glass2O5, pass through heat treatment
Hydroxyapatite crystal can be precipitated, with excellent biocompatibility and bioactivation, other components in composition can be analysed
Other types of crystal out guarantees chemical stability, machinability of material etc., more promising than materials such as metal, aluminium oxide.
Many clinical tests have been carried out so far, and some is up to 6 years as long as, and all achieves gratifying achievement.
This kind of material of new function glass ceramics develops with new technology, high-tech demand, it uses glass technology
Forming and the characteristic preparation of crystal needed for being precipitated by dominated crystallization have piezoelectricity, partly lead, is ferroelectricity, electric light, non-linear etc. various
The material of characteristic.Some major function materials of research have glass for infrared rays ceramics, ferroelectricity and ferromagnetism glass ceramics, mix Cr3+
The transparent glass ceramics of plasma, in addition there are the glass ceramics for electronic device and its sealing-in, be used as catalyst carrier with
Porous doped-glass ceramics of sensor etc..But functional crystal amount of precipitation it is inadequate when, performance will lead to " dilution " effect, material
Though having certain functional characteristics, performance indicator is poor, is not able to satisfy application requirement.Therefore, the crystallization of functional crystal how is improved
Rate and makes material as far as possible and be single-phase or be the emphasis in such investigation of materials containing minimum out-phase.
For glass ceramic material, high-temperature stability and impact strength and toughness are always the emphasis studied.
