The invention discloses a porous ceramic and a preparation method thereof. The porous ceramic is composed of solid mixed powder and organic slurry, and the mass ratio of the solid mixed powder to theorganic slurry is 100:(10-20); the solid mixed powder comprises the following raw materials in parts by weight: 40-60 parts of alumina powder, 5-15 parts of plant ash, 5-15 parts of flour and 20-30 parts of low-temperature glass glaze powder; and the organic slurry comprises the following raw materials in parts by weight: 1-4 parts of polypropylene glycol and 1-16 parts of polyethylene glycol. Theporous ceramic provided by the invention has the characteristics of high through hole porosity, stable porosity, good pore distribution uniformity, high strength and uniform density distribution, anddoes not generate the problems of powder falling, embrittlement, deformation and the like in the use process. The preparation method of the porous ceramic is simple in process, high in repeatability,wide in raw material source, low in raw material and equipment cost and suitable for industrial production, and has an excellent industrial application prospect.
本发明公开了一种多孔陶瓷及其制备方法，所述多孔陶瓷由固体混合粉末和有机浆料组成，所述固体混合粉末与所述有机物浆料的质量比为100：10～20；所述固体混合粉末包括以下重量份数的原料：氧化铝粉40～60份、草木灰5～15份、面粉5～15份、低温玻璃釉粉末20～30份；所述有机浆料包括以下重量份数的原料：聚丙二醇1～4份、聚乙二醇1～16份。本发明中的多孔陶瓷具有通孔孔隙率高、孔隙率稳定、气孔分布均匀性佳、强度高、密度分布均匀的特点，使用过程中不会产生掉粉、脆裂及变形等问题。本发明中的多孔陶瓷制备方法，工艺简单，可重复性高，原料来源广泛，且原料与设备成本低廉，适合产业化生产，具有极好的工业化应用前景。
