Foamed ceramic prepared by using perlite tailings as base material and preparation method thereof
The invention relates to a foamed ceramic prepared by using perlite tailings as a base material and a preparation method thereof, the foamed ceramic is formed by stacking and sintering a plurality of sheets, and the base materials of the sheets are perlite tailings, a foam stabilizer containing alumina and expanded perlite micro powder. The specific gravity of the green body is reduced through the expanded perlite micro powder, so that the foaming expansion rate of the foamed ceramic green body is reduced, and the foamed ceramic is uniformly expanded and keeps a certain shape in the foaming process in combination with the foam stabilizer, so that the foamed ceramic green body is prevented from collapsing due to huge deformation in the foaming process, and the high-temperature foaming of the foamed ceramic under the mold-frame-free condition is met.
一种利用珍珠岩尾矿为基料制备的发泡陶瓷以及制备方法，所述发泡陶瓷由若干薄片叠烧而成，所述薄片的基料为珍珠岩尾矿、含有氧化铝的稳泡剂和膨胀珍珠岩微粉。本申请通过膨胀珍珠岩微粉降低坯体的比重使发泡陶瓷坯体的发泡膨胀率减小，并结合稳泡剂使发泡陶瓷在发泡过程中均匀膨胀并保持一定的形状防止发泡陶瓷坯体在发泡过程中产生巨大变形而塌陷，满足发泡陶瓷在无模框条件下高温发泡。
