SINTERING CONTROL METHOD OF CERAMIC MANUFACTURING
The present invention provides a sintering control method of ceramic manufacturing. The method includes the following steps: S1: preparing a pore-forming agent containing a porogen; S2: mixing the pore-forming agent with a ceramic slurry and forming a greenpart; S3: sintering the greenpart at a first temperature in an oxygen-free environment to form a semi-finished object; and S4: sintering the semi-finished object at a second temperature in an oxygen-containing environment to form a ceramic article. Wherein, the first temperature is higher than the second temperature. While the porogen is a carbon-based material, the second temperature is from 300° C. to 600° C., and the porosity of the ceramic article may reach 30% to 70%. By this method, the property of the ceramic article (including mechanical strength, porosity, pore shape and size) can be designed according to requirement and controlled for quality assurance.
