The following properties make zircon an excellent material for sand casting, investment casting, and die casting:
The advantages of using zircon sand and zircon flour in these foundry processes are:
Zircon and its derivatives have a vast array of applications. The largest market for zircon is the ceramics industry. Approximately 54% of zircon that is produced is used in ﬁnely ground form in the ceramics industry. 14% goes is used by the foundry industry, and approximately 11 - 14% is used in refractory applications.
A growing portion of the zircon mined worldwide is used for the extraction of the metals zirconium and hafnium or their further processing to produce zirconium chemicals. There is a considerable number of further uses and it is clear from emerging research and development that zircon will continue to play an even greater role in the technological advances of the modern era.
The ceramics industry is the largest user of zircon, where it is used mainly in tile production.
Zircon is used in the foundry industry in sand and investment casting.
Zircon and zirconia are used in a wide range of refractory applications.
