Abstract
A low-temp. liquid-phase sintered zirconium oxide toughened ceramics features that the CeO2, Y2O3, or CeO2 + Y2O3 is used as stabilizer, the glass phase in MgO-Al2O3-SiO2 system is used as principal component of sintering assistant, and it is sintered at 1220-1450 deg.C. The compact sintered body has high strength (700-930 MPa), toughness (6-12 MPm1/2) and hardness (Hv) (8-11.5GPa). Its advantages are wide range of raw material's granularity from ultrafine to microns, lower sintering temp., wide range of sintering temp. and high mechanical property similar to that of solid-phase sintered same material.
Description
The present invention is the toughened zirconia ceramics material of low-temp liquid-phase sintering, belongs to the oxide ceramic material field.
R.C.Garvie in 1975 has found that the partially stabilized zirconia ceramics material of CaO is in breaking-down process, its cubic phase (t) changes the martensitic transformation of monocline phase (m) into, can make material obtain higher intensity and fracture toughness property, start the research field of toughened zirconia ceramics.
Discovering subsequently: use Y

2Be stablizer, the superfine powder for preparing with wet chemical methods such as co-precipitation is a raw material, and the cubic phase polycrystal zirconia ceramics of preparation (being called for short TZP) has good mechanical property.Particularly with Y
2O
3For the normal temperature bending strength value of the cubic phase polycrystal zirconia ceramics of stablizer (being called for short Y-TZP) very high; With CeO
2For the toughness and the aging performance of the cubic phase polycrystal zirconia ceramics of stablizer (being called for short Ce-TZP) fine; With Y

3+ CeO
2Be stablizer, the toughened zirconia ceramics comprehensive mechanical performance can be improved.These materials are just obtaining in fields such as communication, machinery, weaving, the energy, sports equipment to use.
But all be to obtain fine and close toughened zirconia ceramics material by 1500-1650 ℃ of high temperature solid-phase sintering at present both at home and abroad, concrete sintering temperature is relevant with the kind and the content of stablizer.This is for the widespread use and the suitability for industrialized production of material, and its subject matter is:
1. employing high temperature solid-phase sintering, the grain size of material are difficult to control;
2. owing to the temperature height of solid state sintering, to the requirement height of equipment, energy consumption is big;
3. solid state sintering need adopt the powder (the powder primary particle size is 30-40nm, aggregate particle size＜0.5 μ m) of wet chemical method preparations such as co-precipitation.This powder price height, and powder characteristic is difficult to stablize when producing in enormous quantities.
The present invention is the production technique that adopts general stupalith, comprises pre-treatment, batch mixing, the moulding of raw material, steps such as sintering and performance test, and specific implementation method is:
