Over the years we have successfully claimed the market credibility and the reliance of our esteemed clients by offering an outstanding gamut of Zinc Oxide including- Zinc Oxide 99.7%, Zinc Oxide Grade (99.5%), Zinc Oxide Grade (99.0%) and Zinc Oxide Grade (97.0%). Our entire range includes:


Our comprehensive range of Zinc Oxide (ZnO) bears the following attributes:

• Inorganic compound
• Inexpensive
• Relatively abundant
• Chemically stable
• Easy to prepare
• Non-toxic
• Replacement for toxic, expensive transistors in the LED space
• Can be processed using various manufacturing process
• Impedes the growth of fungi, mildew and mold
• Exhibits semi conducting, piezoelectric, and pyroelectric multiple properties

Following are some of its Chemical & Physical Properties:

• Molecular weight: 81.37
• Boiling point: Sublimes at normal pressure.
• Specific gravity: 5.607 at 20 degrees C (68 degrees F
• Density: 5.606gm/cm, Solid
• Melting point: 1975 degrees C (3587 degrees F)
• Vapor pressure: < 0 (mm Hg)
• Solubility: Practically insoluble in water; soluble in dilute acetic or mineral acids, ammonia, ammonium chloride, ammonium carbonate, and fixed alkali solutions; insoluble in alcohol.
• Evaporation rate: By use of a mass spectrographic method, the rate of evaporation of zinc oxide is measured as a function of temperature both with and without electron bombardment of the surface being evaporated. A definite increase was observed in the evaporation of zinc oxide. The enhancement of the evaporation rate of zinc oxide increases slowly at first and then rapidly with increasing temperature.
• pH: 6.95

Chemical Data:

• ZnO occurs as white powder commonly known as zinc white or as the mineral zincite. The mineral usually contains a certain amount of manganese and other elements and is of yellow to red color.[2] Crystalline zinc oxide is thermochromic, changing from white to yellow when heated.
• Zinc oxide is an amphoteric oxide. It is nearly insoluble in water and alcohol, but it is soluble in (degraded by) most acids, such as hydrochloric acid:

ZnO + 2 HCl → ZnCl2 + H2O

• Bases also degrade the solid to give soluble zincates:

ZnO + 2NaOH + H2O → Na2 (Zn (OH) 4)

• ZnO reacts slowly with fatty acids in oils to produce the corresponding carboxylates, such as oleate or stearate. ZnO forms cement-like products when mixed with a strong solution of zinc chloride or with phosphoric acid, owing to formation of oxysalts.
• ZnO decomposes into zinc vapor and oxygen only at around 1975°C, reflecting its considerable stability. Heating with carbon converts the oxide into zinc vapor

ZnO + C → Zn + CO

• Zinc oxide reacts violently with aluminum and magnesium powders, with chlorinated rubber and linseed oil on heating causing fire and explosion hazard.
