Zircon - an overview | ScienceDirect Topics

Deze pagina vertalen

Zircon is a naturally occurring material, ZiSiO 4, and is found in heavy mineral deposits such as illmanite, rutile, monazite and garnet as river or beach sands. High-grade zircon melts at about 2190 °C, softens between 1600 °C and 1800 °C and is volume stable up to 1750 °C.

The mean values (251,300C) of specific heat of these molds are 0.25CGS unit for silica sand, 0.26CGS unit for olivine sand, 0.18CGS unit for zircon sand and 0.21CGS unit for chromite sand. With the measured values of thermal conductivity, specific heat and mold density, thermal diffusibility and heat diffusibility of each mold were calculated.

Heat treating of zircon is routinely done, usually stable and undetectable except the fact that colorless and blue zircons do not occur in nature. Some heated orange stones revert back to brown within a short period of time (overnight) after heating.

Calcined alumina is an alternative in fabricating super refractories but it has much higher thermal expansion and greater heat conductivity. Zircon sand (which is milled to produce zirconium silicate powders) has become so expensive that major manufacturers are considering, or are already diluting their products with other materials (like kaolin).

Zircon. The mineral zircon (zirconium silicate) generally occurs in nature as a crystal. Most of the naturally occurring radioactive material (NORM) found in zircon is uranium and thorium, which is created during the crystallization of the mineral from the molten host rock when it is initially formed.
