Zircon is the natural form of Zirconium Silicate. Zircon is used to produce zirconium metal and zirconium dioxide. Zircon sand has a low expansion coefficient and is very stable at high temperatures. It is used as a refractory material in many foundry and casting applications. One of its most common uses is in the production of ceramics. � Zirconium is used in a variety of metal products that require a resistance to heat and corrosion. It is used to make high-performance alloys, specialty steel, lamp filaments, explosive primers, computer equipment and many electronics components.
Zircon sand finds applications to be used in ceramics, refractory, foundry, electronics, zirconium compound, and other fields, it is also used in the preparation of nuclear reactor structural materials and control rod with zirconium and hafnium as irreplaceable raw minerals making it a strategic mineral.
It is used in ceramics as a major end-user, zircon sand is used as a glaze emulsion is ceramics such as glazed floor tiles, wall tiles, sanitary ware, and tableware.
Properties of Zircon Sand
Zircon is crystal and shows the structure of the quarter column. It usually occurs with ilmenite rutile, sillimanite, etc. in beach sand and is refined by water, electricity, and magnetic beneficiation process.
Pure zircon is a colorless and translucent crystal. It appears yellow, orange, red, and brown with different origins. Its hardness is 7.8, specific gravity 4.6-4.71, refractive index 1.93-2.01, and the melting point of 2550 C.
INTRODUCTION:
Zircon sand, also known as zircon, is a mineral composed mainly of zirconium silicate (ZrSiO4). Pure zircon sand is a colorless transparent crystal.
FORM OF ZIRCON
ZIRCON SAND
ZIRCON POWDER
APPLICATION:
To be used in Ceramics. Opacity, whiteness, wear resistance and moisture resistance make it a key component of ceramic tiles, sanitary ware and tableware.
To be used in refractory industry to protect the interior of high-temperature furnaces
To be used in foundries and precision casting processes for the casting of metals and alloys into various products due to the thermal stability, high melting point and abrasion resistance provided by zircon.
Another important application is the production of a broad range of zirconia chemicals, which in turn, have a diverse range of end uses including ceramics, refractory, catalysts, coating electronics and biomedical related products.
Some zircon is used as an x-ray filter and as a polishing agent in the production of silicon wafers for the manufacture of semiconductor components such as integrated circuits (computer chips).

Zircon sand is a tetragonal system with a square pyramidal shape with a specific gravity of 4.6~4.71, a uniform Mohs hardness of 7-8, a refractive index of 1.93-2.01, and a melting point fluctuating within 2190~2420 °C depending on the impurities contained. It is a tetragonal system, often in the form of a well-developed cone-shaped small square cylinder, which is also irregularly granular. Sexually brittle, fractured shell-like. It is a high quality refractory material. It is symbiotic with ilmenite, rutile, monazite and xenotime in coastal sand, and is obtained after sorting by water separation, electric selection and magnetic separation.
Zircon Sand is generally found inland of ancient coastlines, some of which can be found very far inland, where the heavier mineral sands formed hardened deposits. These deposits are typically mined via dry or wet (dredge) mining techniques.

zircon as a material for industrial ceramics, refractories (furnace or reactor lining materials that are resistant to high heat), to dyes.
the use of zircon is developing in a number of industrial sectors, including: ceramic Industry, PSZ (Partially Stabilized Zirconia) glass industry, Zircon flour industry (micronized zircon), zirconium chemical industry, Refractory brick industry Printing sand industry.
the use of micronized zircon or zircon powder in ceramic products accounts for almost half of the national consumption of this mineral. In the manufacture of ceramics, zircon flour serves as an opaque glaze for household items and ceramic tiles. Meanwhile, in the glass industry, zirconia (fused zircon) is used to produce glasses with special compositions, such as optical glass, fiber glass, color TV glass, and so on.
In addition, the use of zircon is quite high in the metal industry. This mineral is used in the metal industry because it has heat-resistant properties. In practice, zircon flour is used to coat metal products, such as steel and bone iron, especially dry coating to produce kitchen and bathroom products. The use of zircon flour is also applied in the production of refractory bricks used to line steel or glass smelting furnaces. Zircon is also used in the nuclear sector. In this field, zircon is used as a cladding material for nuclear reactor fuel. As a coating material, zircon can withstand very high heat which is the result of fusion reactions in nuclear reactors.
