: Song Dynasty ceramic filter material is made of high-quality high-alumina bauxite through high-temperature calcination, crushing, electrolytic melting and other processes. <: Generally, homogeneous filter material is used for water treatment and has the best effect. It has a smooth surface, low filtration resistance, wear resistance, non-breaking, non-caking, easy to regenerate, and generally does not need to be replaced. <: , used as proppant for downhole fracturing in oil fields. It has a smooth surface, high strength, acid and alkali resistance, strong conductivity, good permeability and long service life. &<: Main technical indicators of ceramsite sand (fracturing proppant):
