ZIRCON

BRIOREF®

Zircon is a dense, chemically inert, highly refractory, alluvial sand with low thermal expansion and conductivity coefficients, as well as a high refractive index.

BRIOREF® PRIMAZIR is used in abrasives, ceramics (opacifying enamels), chemistry, classical and precision foundries, friction, metallurgy, refractories, welding electrodes, glass.

In the form of cut crystal, it is sold in jewellers shops in its natural form known as “Zircon” and in its synthetic form known as “Zirconia”.

Zircon, in most of the turbo-jet engines of airliners, is moulded and it is also included in the composition of automobile brake pads.
