Title:
LOW-MELTING-POINT POROUS CERAMIC MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/142168
Kind Code:
A1
Abstract:
A low-melting-point porous ceramic material and a preparation method therefor. The porous ceramic material has a firing temperature of 680-830ºC and a porosity of 24-42%, and the raw materials of the porous ceramic material are composed of a temporary binder and a raw material powder. With the synergistic effect of all the raw material components, the resulting product has advantages such as a simple sintering process, a good mechanical strength, no need to add a pore-forming agent and being capable of generating pores, such that problems such as a mismatched refractoriness between the binder and the pore-forming agent, a poor heat dissipation capacity and a poor air permeability are effectively solved, and the service life and the holding force of the porous ceramic material can be improved, wherein the firing temperature thereof is only 680-780ºC, and the porosity can reach up to 42% without the addition of a pore-forming agent, while maintaining a good compressive strength, bending strength and hardness.
