Problems solved by technology
A large number of applications lead to more waste ceramics and recycled materials, which not only causes environmental pollution, but also wastes ceramic resources. However, the inherent brittleness of zirconia limits the reuse of regenerated zirconia ceramics, which requires the development of zirconia. The ceramic waste is modified by the recycling process to prepare wear-resistant and crack-resistant daily-use ceramic products to meet the needs of daily life

Embodiment Construction
[0018] A method for preparing porous zirconia ceramics infiltrated with glass powder, comprising the following specific steps:
[0019] (1) Crush the zirconia return material, pass through a 200-mesh sieve, add an appropriate amount of deionized water, stir evenly, and use a magnetic field strength of 1000 gauss to remove iron for magnetic flotation to remove iron impurities, and then put it in a ball mill to continue Ball milling for 40 minutes, and finally spray drying to obtain treated zirconia powder;
[0020] (2) Stir 90g of treated zirconia powder with 5g of yttrium trioxide and 5g of ammonium bicarbonate powder evenly, then add 2g of polyvinyl alcohol, mix in a mixer for 30 minutes and dry under a pressure of 300MPa Press molding, and then calcined at 550 degrees Celsius for 90 minutes, then put it into a microwave sintering furnace, vacuumize, nitrogen, control the microwave sintering temperature of 1200 degrees Celsius for microwave sintering, and keep it warm for 30 ...

Abstract
The invention discloses a preparation method of regenerated zirconia porous ceramic by glass powder permeation. The prepared regenerated zirconia porous ceramic by the glass powder permeation solves the treatment problems of waste zirconia ceramics and zirconia ceramic reclaimed materials; a prepared domestic ceramic product is excellent in mechanical property; the brittleness of the zirconia ceramic is improved; and the domestic ceramic product with good compactness and fracture toughness is obtained.
Description
technical field [0001] The invention relates to the technical field of daily-use ceramics, in particular to a preparation method of regenerated zirconia porous ceramics by infiltration with glass powder and a preparation method thereof. Background technique [0002] Among ceramic materials, zirconia ceramics are more excellent in strength and fracture toughness than other ceramic materials, so they are widely used in the field of structural ceramics. The main products are grinding balls, dispersing and grinding media, zirconia molds, wear-resistant knives, clothing buttons, watch cases and straps, bracelets and pendants, and other room temperature wear-resistant parts. A large number of applications lead to more waste ceramics and recycled materials, which not only causes environmental pollution, but also wastes ceramic resources. However, the inherent brittleness of zirconia limits the reuse of regenerated zirconia ceramics, which requires the development of zirconia. The ...
