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 .
Refractories – Used for its high thermal stability and nonwetability against molten metals. Products include bricks used to line steel making furnaces and casting channels for refined steel continuous castings. Advantages of Using Zircon Sand: Resists metal penetration and reaction with most alloys
Zircon sand has the lower thermal expansion, higher thermal conductivity, and stronger chemical stability than other common refractory materials, and highquality zircon and other adhesives have a good bond and used in the foundry industry. Zircon sand is also used as bricks in glass kilns.
Zircon standard grades. Zircon Sand is typically available in one standard grade. Zircon flour is available in 325# and 200# as standard. Other grades may be available upon request. Contact your local Sales Representative for more information. Zircon packaging. Both .
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.
Iluka Resources of Australia is the largest producer of zircon sand with 9 mines in Australia and 2 mines in the USA. Iluka tends to set the benchmark in global pricing for zircon sand and at the start of 2008 the price was at USD 800850/mt CIF China and ended the year at USD 850900/mt CIF China.

Florida Zircon Sands Product Information Chemours™ Florida zircon sands are naturally occurring rounded grain sands mined from our heavy mineral deposits in northeast Florida. The zircon sands are washed to give clean products free from dirt and ultrafines and .
thermal conductivity of YTZP based composites with zircon, fabricated from the powder with more than 15 vol.% content of cordierites, which appears to be lower than that of pure zirconia, despite the mixed materials exhibit high thermal conductivity. The DTATG examination confirmed excellent stability of the composite at ele
The Thermal Conductivity of chromite sand is higher than the other commercially available foundry moulding sands. This results in a mild chilling of the surface and a thicker solidified skin. This thicker skin improves the casting surface and reduces the likelihood of casting defects.
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"
Zircon sand has the lower thermal expansion, higher thermal conductivity, and stronger chemical stability than other common refractory materials, and highquality zircon and other adhesives have a good bond and used in the foundry industry. Zircon sand is also used as bricks in glass kilns.
The arrangement of components is known to be affected by particle size distribution, average size and shape. In this study, an experimental system using the lineheatsource method was designed and effective thermal conductivities of molding sands at temperatures up to 750°C were measured.
` It is ability of the molding sand to retain its properties during storage. Besides these specific properties the molding material should be cheap, reusable, coefficient of expansion, durability and should have good thermal conductivity. 7 Compiled by Prof. Amruta A. Rane (Asst. Prof., DJSCE)
