muscovite mica content for Sample LB559585 (Target 1) that may be at the expense of feldspar due to retrograde alteration during shearing. The clay content of Sample LB559587 (Target 5) is relatively high due to weathering. The identification of "graphite clay" may be due possibly to .
Glass: Feldspar is an important ingredient in the manufacture of glass and an important raw material as well, because it acts as a fluxing agent, reducing the melting temperature of quartz and helping to control the viscosity of glass. The alkali content in feldspar acts as flux, lowering the glass batch melting temperature and thus reducing ...

Oct 29, 2013· High purity quartz is a highly specialized and, in many ways, highly secretive market. It refers to material of ultra high purity – generally higher than % SiO 2 with impurities of less than 50 ppm. The highest purity product based on natural quartz that is currently available has a purity of % with boron as low as 40 ppb.
