Acid washed beads are oven dried and baked prior to bottling, at which time they are suitable for most applications. Available in both silica (glass beads) and zirconium oxide in nine sizes. Glass beads are good for general grinding applications while zirconium beads .
the ability to use the ubiquitous monosilicic acid Si(OH) 4 for the formation of species specifically structured, silicabased exo or endoskeletons (1). This interesting biological phenomenon is mediated by cellular organic (macro)molecules that accelerate silicic acid polycondensation and control morphogenesis of the forming silica (2).

Raw material is washed for taking out the clay material which is useful in making the tiles. In the raw material about 10% is clay which is supplied to the ceramic factories. From the raw material different size of silica sand are separated by different size of sieve. Sand size of 30 mesh to 80 mesh (500 micron) is used in the glass industries.
Cation is a negatively charged resin bead (about 23 microns in diameter). It is regenerated with a 67 percent hydrochloric acid solution. When cation resin first enters the deionization process, positively charged hydrogen ions(H+) are attracted to the negative "exchange sites" on the cation resin beads.

types of silica was investigated. Earlier works [28] showed a possibility of fractioning dextrans of average MW 40 kDa into low and high fraction (25 and 70 kDa respectively) using mesoporous silica of particle size 200–500 micron. Bare silica was also investigated in HPLC mode (particle size 5 micron) [29] and SEC properties was showed for dex
Useful for disrupting yeasts such as Saccharomyces by bead beating, 400 µm acid washed silica beads are a good choice for standard laboratory beads are more economical than zirconium silicates and oxides, while often as effective. Acid washed silica beads are treated with acidified water to remove fine particles, dust, and other impurities typically found in untreated beads.
