Zircosil is the registered name of Jyoti Ceramic Industries Pvt. Ltd. for their proprietary formulated Zirconium Silicate composite, specially developed for upper medium density (4.6 gm/cc) ceramic micro milling beads used for wet milling / dispersion of formulations.

For many years Jyoti has been manufacturing Zirconox, a wonder ceramic micro milling beads and have gained world-wide popularity for this unique product. Over the period of time Zirconox has established a distinct identity in the ceramic milling bead market and Zirconox as a brand name has almost become synonymous with ceramic micro milling beads.

Looking to the market needs for medium density, long-lasting, cost-effective ceramic milling beads, we started an extensive research to develop suitable ceramic milling beads to meet the specific segment of customers who have bead mills but not suitable to carry the load of Zirconox high density (6.2 gm/cc) beads. We finally succeeded in developing Zircosil ceramic micro milling beads.
