We are engaged in manufacturing, exporting and supplying Boric Acid that is formulated as per the set standards using quality methods. The clients can avail the Boric Acid from us at affordable price in proper packaging of varied quantity.

These solubilities are influenced by the presence of other substances. For example, sodium chloride, lithium chloride and mineral acids reduce solubility, whereas sodium sulfate, sodium nitrate, potassium nitrate, potassium sulfate and potassium chloride increase it.

Technical Description

  • Synonymy : ORTHO-BORIC ACID
  • Formula : H3BO3
  • Molecular Weight : 61, 84
  • Crystallization : It crystallizes in tryclinium-pinacoidal scales
  • Fusion Point : 170o C
  • Relative Density : 1, 435 to 15oC
  • Dissolving Heat : 5400 cal/mol at 18o C

Zircon Sand

Zircon is a hard, glassy mineral used for the manufacture of ceramics and refractories and in a range of other high-tech industrial and chemical applications. It is used extensively for ceramic glazes - most commonly seen in kitchen tiles, dinnerware, bathroom products and decorative ceramics. Industrial ceramics made using zircon are used for heat and abrasion resistance. Some industrial ceramics are referred to as refractories - materials that retain their physical shape and chemical composition when subjected to very high temperatures. With a melting point of around 18, 000C, these refractories are used as linings to protect furnaces and kilns for smelting metals and for the manufacture of chemicals. Resistance to corrosion and erosion makes zircon products ideal for use in the chemical industry and in desalination plants. One of the early discoveries for zircon use was for the manufacture of phosphates for kidney dialysis. Zircon compounds have a very low toxicity and are now increasingly preferred in the manufacture of some foodstuffs, pharmaceuticals and medicines. It is even used in toothpaste to prevent tooth decay

Zircon is a key raw material used in the production of opacifiers, glazes and frits, floor and decorative tiles, sanitary ware, glass and steel refractories, metal castings and specialized glass. Consumption of zircon products in the manufacture of faceplates for TV monitors and computer screens continues to increase, particularly in developing countries. The increased use of zirconium chemicals and zirconia in various applications continues with China being in the forefront of new production facilities to service these industries. Recently announced construction of additional nuclear power stations in China and South Korea will create continued demand for zirconium metal in this much-specialized market. The current driving force in zircon demand is in both China and India where the various consuming industries have expanded across the board, increasing usage to the extent that global demand now exceeds global production capacity. A rundown of stock levels both in producer and consumer hands has created a severe shortage of material to the extent that some industries have been required to close. This imbalance will continue to exist until the arrival of new production sources, currently planned to come on line in 2006.

It is predominantly used as a glaze material and as an opacifier to provide shine and brightness for crockery, sanitary ware, Ceramic tiles, other decorative ceramic products and is also widely used in television and computer screens. Resistance to corrosion and erosion makes zircon products ideal for use in the chemical industry and in desalination plants.

Uses : The Industrial zircon ceramics are extensively used as linings to protect furnaces and kilns for smelting of metals because they can retain their physical and chemical composition even when subjected to high temperatures. Zircon application is mainly confined to mold faces and cores, which directly come in contact with molten metal. Zircon sand helps in minimizing the penetration of mold by the molten metal and thus ensures that the casting gets a good surface finish.
