Abstract

The effect of technological parameters on the characteristics of filtering acid-resistant ceramics is investigated. A technology has been developed for producing large-sized products from ceramic electric-grade material of subgroup 110 by aqueous casting into gypsum molds. The water filtration rate was 0.02 – 0.03 ml/(cm2·h), the percentage of pores greater than 1 µm was 8 – 10%, and the average pore size was 0.04 – 0.06 µm. The variation in the pore structure of ceramic samples made of nanostructured aluminum hydroxide has been studied. The potential for their use to create ultraporous coatings is shown.

用微孔和纳米孔过滤耐酸陶瓷
研究了技术参数对过滤耐酸陶瓷特性的影响。已开发出一种技术,通过在石膏模具中进行水浇铸,利用 110 亚类的陶瓷电级材料生产大型产品。水过滤率为 0.02 - 0.03 ml/(cm2-h),大于 1 µm 的孔隙百分比为 8 - 10%,平均孔径为 0.04 - 0.06 µm。对纳米结构氢氧化铝陶瓷样品孔隙结构的变化进行了研究。结果表明,这些样品具有制造超多孔涂层的潜力。
