Abstract

Samples of two-layer ceramics based on polydisperse powder of the pearlite mineral and foam silicates possessing high compressive strength up to 50 MPa, thermal stability up to 1150°C, and water permeability of 272 m³/h m² bar have been obtained. According to the X-ray powder diffraction analysis, the supporting substrate material is X-ray amorphous. The average pore size of the supporting substrate is 40 µm, while the average pore size of the modifying layer is 17 µm according to the bubble method and electron microscopy. The obtained materials are promising for use as substrates of microfiltration, ultrafiltration, and nanofiltration membranes.

基于珍珠岩和泡沫硅酸盐的过滤膜高强度陶瓷基板

制备了珠光体矿物和泡沫硅酸盐多分散粉末双层陶瓷样品，其抗压强度高达50 MPa，热稳定性高达1150℃，透水性为272 m3/h m2 bar。根据x射线粉末衍射分析，支撑衬底材料为x射线非晶态。气泡法和电镜结果显示，支撑基板的平均孔径为40µm，修饰层的平均孔径为17µm。所获得的材料有望用作微滤、超滤和纳滤膜的底物。
