Zircon sand

INTRODUCTION:
Zircon sand, also known as zircon, is a mineral composed mainly of zirconium
silicate (ZrSiO4). Pure zircon sand is a colorless transparent crystal.
FORM OF ZIRCON
ZIRCON SAND
ZIRCON POWDER
APPLICATION:

To be used in Ceramics. Opacity, whiteness, wear resistance and moisture
resistance make it a key component of ceramic tiles, sanitary ware and
tableware.
To be used in refractory industry to protect the interior of high-
temperature furnaces
To be used in foundries and precision casting processes for the casting of
metals and alloys into various products due to the thermal stability, high
melting point and abrasion resistance provided by zircon.
Another important application is the production of a broad range of
zirconia chemicals, which in turn, have a diverse range of end uses
including ceramics, refractory, catalysts, coating electronics and
biomedical related products.
Some zircon is used as an x-ray filter and as a polishing agent in the
production of silicon wafers for the manufacture of semiconductor components
such as integrated circuits (computer chips).
