Zirconium Beads are ideal for homogenizing soft to medium-tough tissues. Zirconium Oxide beads have a slightly higher density (5.5g/mL) and are good for homogenizing soft to medium-tough tissue. Zirconium Beads are available in 4 mL and 1 lb packages with RNAse free options and various diameters.
Fused zirconia (zirconium oxide) is produced through the reduction and fusion of zircon sand (zirconium silicate). Zircon is mixed with coke and heated to its fusion point (in excess of 2,800 ̊C) in an electric arc furnace where it dissociates to zirconium oxide and fumed silica.
The most important market for zircon by volume is the ceramics industry. Within this sector, the principal use of zircon is as an opacifier (or whitener) for the ceramic body and surface. As a fine powder, zircon can be used directly in ceramic mixtures to increase the whiteness of the entire ceramic body or used in engobes to produce a white and opaque layer that hides the colour of the body. It’s also used as a raw material in ceramic glazes to increase their opacity, or in frit compositions used to produce glossy, opaque, white glazes. When used in surface glazes, zircon significantly enhances resistance to abrasion and chemical attack.
