What Is a Porous Ceramic?
Porous ceramic is a type of ceramic material characterized by its numerous fine pores.
This material offers various functions including water absorption, adsorption, insulation, low thermal conductivity, and filtration capabilities. The pores within the ceramic draw in water or gas, enabling water absorption and adsorption, while the air pockets in these pores provide insulation by reducing heat conduction. Consequently, porous ceramics are utilized in a variety of applications, such as filters, bubble generators, catalyst supports, insulation materials, and medical supplies.
The manufacturing of porous ceramics can involve techniques such as sintering, the solvent substitution method, and the bubble method, which allow for precise control over the size, shape, and distribution of the pores. Notable characteristics of porous ceramics include their lightweight nature, high strength, resistance to heat and chemicals, and ease of processing. These attributes make porous ceramics exceptionally versatile, finding uses in numerous areas including as filters and catalyst supports.
