Abstract:
A microwave (MW) method of hydrothermal synthesis of zirconium silicate is developed. At low temperature (240°C), nuclei of crystalline phase of zirconium silicate (zircon) are obtained. Some optical characteristics of the synthesized product are determined. The dependence of the diffuse reflectance on radiation is studied at low temperatures (90 K) and pressures (10-5 - 10-6 Pa). Based on gravimetric, X-ray and thermographic studies is revealed that the synthesis of zirconium silicate from water-soluble salts of initial components in microwave ovens promotes the formation of zircon at lower temperatures. MW synthesis of zirconium silicate ensures obtaining of nanosized zircon powder after heat treatment at 1200°C.
