无机多孔非金属矿 ,按孔径及其应用特点可划分为纳米级 (1～ 10 0nm )、微米级 (0 .1～10 0 μm)及毫米级 (0 .1～ 1mm)等三种类型。微米级多孔非金属矿主要有硅藻土、轻质蛋白石、多孔凝灰岩、多孔硅质岩等 ,大都分布于地台活化区内 ,为后地台稳定条件下形成。它们的物相主要为蛋白石、微晶石英或流纹质玻屑等 ;化学成分上具有高硅、低铝铁等特征 ;孔隙结构除具有孔径相似、孔形态丰富、孔隙率大、堆密度小及多开孔等相似性外 ,在微米级孔径范围内 (0 .1～ 10 0 μm) ,孔隙的大小、形状及抗压强度等方面也具有相异性。因此它们具有与纳米级和毫米级多孔非金属矿不同的应用领域。
Inorganic porous nonmetallic ore can be divided into three types of nanometer (1 ~ 100nm), micron (0 ~ 1 ~ 100μm) and millimeter (0 .1 ~ 1mm) according to the aperture and its application characteristics. Microporous porous non-metallic mineral mainly diatomite, light opal, porous tuff, porous silicalite, etc., mostly distributed in the activation area of the platform for the formation of stability after the platform. Their phases are mainly opal, microcrystalline quartz or rhyolite glass and so on; chemical composition of high silicon, low aluminum iron and other characteristics; pore structure except with similar pore size, pore morphology, porosity, bulk density And multi-open holes and other similarities, but also in the micron-scale pore size range (0.1 ~ 10 0 μm), the size of the pore, shape and compressive strength and so on are also dissimilar. They therefore have different applications than nanoscale and millimeter porous non-metallic ores.
