15-08-2020 · Column chromatography is frequently used by organic chemists to purify liquids (and solids.) An impure sample is loaded onto a column of adsorbant, such as silica gel or alumina. An organic solvent or a mixture of solvents (the eluent) flows down through the column. Components of the sample separate ...

74% fused silica, 24% zircon, 2% alumina. The highly versatile blend of 74% fused silica, 24% zircon and 2% alumina can be used in Equiax, directionally solidified or single crystal casting, and with alloys that have high temperature pre-heats. It is often used with most nickel-based, DS and SX alloys.
