Zircon (/ ˈ z ɜːr k ɒ n / or / ˈ z ɜːr k ən /) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate, and its corresponding chemical formula is Zr SiO 4. A common empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x (OH) 4x–y.

Zircon is widely used in the foundry industry, mostly in the form of SAND and FLOUR (milled sand) for casting and refractory applications. Zircon''s properties make it ideal as a moulding base material for sand casting and investment casting, in addition to use as mould coating in die casting and in refractory paints and washes to reduce the wettability of other foundry sands.
Thermal Conductivity of Moulding Sand with Chemical Binders, Attempts of its Increasing Article (PDF Available) in Archives of Metallurgy and Materials 60(1):351357 · March 2015 with 1,531 Reads
Thermal conductivity is a material property that describes ability to conduct conductivity can be defined as "the quantity of heat transmitted through a unit thickness of a material in a direction normal to a surface of unit area due to a unit temperature gradient under steady state conditions"
Thermal Conductivity of Zirconium Zirconium is a lustrous, greywhite, strong transition metal that resembles hafnium and, to a lesser extent, titanium. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion.

Zircon is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate and its corresponding chemical formula is ZrSiO4. Hafnium is almost always present in quantities ranging from 1 to 4%. The crystal structure of zircon is tetragonal crystal class.
Looking for zircon sand? Find out information about zircon sand. A refractory sand consisting principally of zirconium silicate and characterized by low thermal expansion and high thermal conductivity Explanation of zircon sand
This high ionic conductivity (and a low electronic conductivity) makes it one of the most useful electroceramics. Zirconium dioxide is also used as the solid electrolyte in electrochromic devices. Zirconia is a precursor to the electroceramic lead zirconate titanate (PZT), which is a highK dielectric, which is found in myriad components.

This paper describes a determination of thermal conductivity of sands at steady state and cooling stage conditions. Determination of thermal conductivity of sands (dry coarse sand, saturated coarse sand, dry fine sand, and saturated fine sand) at cooling stage conditions gives similar results to the generic published values. 1. INTRODUCTION
The values of thermal conductivity of the molds which consisted of silica, zircon, chromite sands decrease gradually from room temperature to 1,000°C. The mean values of thermal conductivity of these molds are unit for silica sand, unit for olivine sand, unit for zircon sand and unit for chromite sand.
