Porous ceramic and preparation method thereof
The invention discloses a porous ceramic and a preparation method thereof, and relates to the technical field of porous ceramics. The porous ceramic is composed of first granulated particles and second granulated particles, and the first granulated particles comprise the following components in parts by weight: 40-60 parts of aggregate, 35-45 parts of a pore forming agent, 2-8 parts of a sintering aid, 0.1-0.5 part of a stabilizer, 10-30 parts of a binder, 1-5 parts of a dispersant and 0.1-5 parts of anhydrous sodium metasilicate; the second granulated particles comprise the following components in parts by weight: 45-65 parts of aggregate, 35-40 parts of a pore forming agent, 2-8 parts of a sintering aid, 10-30 parts of a binder and 1-5 parts of a dispersing agent. According to the porous ceramic and the preparation method thereof provided by the invention, the anhydrous sodium metasilicate is introduced, so that the sintering temperature is reduced by 100-200 DEG C under the condition of ensuring that the aperture, porosity and strength of the porous ceramic are controllable, the energy consumption is greatly reduced, and the economic benefit is obvious.
本发明公开一种多孔陶瓷及其制备方法，涉及多孔陶瓷技术领域。该多孔陶瓷由第一造粒颗粒与第二造粒颗粒组成，所述的第一造粒颗粒，包括以下重量份组分：骨料40‑60份，造孔剂35‑45份，烧结助剂2‑8份，稳定剂0.1‑0.5份，粘结剂10‑30份，分散剂1‑5份，无水偏硅酸钠0.1‑5份；所述的第二造粒颗粒，包括以下重量份组分：骨料45‑65份，造孔剂35‑40份，烧结助剂2‑8份，粘结剂10‑30份，分散剂1‑5份。本发明提供的多孔陶瓷及其制备方法，通过引入无水偏硅酸钠，在保证多孔陶瓷孔径、孔隙率及强度可控的情况下降低了烧结温度100～200℃，大大降低了能耗，经济效益明显。
