(1) biomedical applications
In dentistry, materials or components used in the oral environment are required to withstand oxidation for a long time.
Maintain stability, but also need to have good machinability and plasticity. Ti3SiC2 is an existing ceramic material
It has metal properties and good biocompatibility, which makes it possible to be used in human body. Ti3SiC2 can be machined to precisely sized threads and can be made into implants without lubricant
Or prosthesis and so on in oral medicine clinical application. Elastic Modulus of Ti3SiC2 and Zirconia (1.9×105MPa)
It is closer to tooth enamel or dentin than to enamel, which increases its potential for application in post or porcelain inner crowns.
The Ti3SiC2 material obtained from self-propagating high temperature contains porous tissue, which may be easier to organize and bind to.
The low coefficient of friction makes it possible to use it in orthodontic applications to increase slippability and reduce friction resistance. Corrosion resistance
Antioxidant property is an important condition for this material to be used in oral environment and maintain its stability. The material
And porcelain powder are ceramic materials, the combination degree may be better than the combination of metal and porcelain, so for porcelain teeth
The inner crown, perhaps more widely used.
However, in the currently known preparation methods of Ti3SiC2, the preparation process must be improved to get pure
Ti3SiC2 block, and then understand more accurate properties of the material. And the biocompatibility of the material
Further laboratory and clinical studies are needed to confirm the clinical usefulness of Dental and Dental.
(2) the application of refractory materials
With the popularization of rapid firing technology in ceramic industry, the cycle of kiln furniture is getting shorter and shorter.
Therefore, it is necessary to continuously improve the thermal shock resistance of kiln furniture materials to meet the requirements of ceramics
Development needs of industrial rapid firing technology. Kiln furniture as a kind of high – grade refractory material, its quality is good or bad
The quality of fired products has an important effect. Ti3SiC2 ceramic material is not sensitive to thermal shock, its unique
Both the layered structure and the plastic behavior at high temperature can relieve the thermal stress. The material went through △T=1400℃
The residual strength of thermal shock is still above 300MPa, and the best thermal shock resistance can withstand a temperature difference of 900℃.
At the same time, Ti3SiC2 ceramic material has good chemical corrosion resistance, easy processing, low relative cost of raw materials
The advantages make it an ideal kiln furniture material to be developed.
