Abstract
Various compositions in MgO-ZrSi04 and CaC03-MgO-ZrSi04 systems heated
up to 1450° for different periods were studied. While in both the systems, there was
complete decomposition of zircon under suitable conditions, it was found that either the
magnesite-zircon composition in the molar ratio of 2:1 or the dolomite-zircon composition
in the molar ratio of slightly greater than 1:1 may be used for industrial applications.
The suitability, in the decreasing order, of the three systems studied was CaC03-
ZrSi04, CaC03-MgO-ZrSi04 and MgO-ZrSi04. The various products of decomposition
were also identified with the help of chemical and X-ray analysis.
