Chemical Properties Of Zinc Hydroxide Cas 20427-58-1

Zinc hydroxide is an amphoteric inorganic hydroxide with the chemical formula Zn(OH)₂ and a molecular weight of 99.39; it consists of divalent zinc ions (Zn²⁺) and two hydroxide ions (OH⁻). As a typical amphoteric hydroxide, zinc hydroxide possesses unique chemical properties: it dissolves in strong acids to form zinc salts, dissolves in strong alkalis to form zincates, and dissolves in excess ammonia water to form zinc ammonium complexes ([Zn(NH₃)₄]²⁺), but is very slightly soluble in water.

Product Application Of Zinc Hydroxide Cas 20427-58-1

  1. Chemical intermediates: It is primarily used in the preparation of high-purity zinc oxide and various zinc salts; also used as a precipitating reagent in chemical analysis and as a catalyst support in organic synthesis.
  2. Rubber industry: Zinc hydroxide is used as a rubber vulcanisation activator and reinforcing agent to improve vulcanisation efficiency and enhance rubber strength, abrasion resistance and anti-ageing properties.
  3. Pharmaceuticals and personal care: Zinc hydroxide is used in the manufacture of anti-inflammatory and anti-itching topical skin preparations, dental impression materials and medical wound dressings; can be used as an astringent and sunscreen additive in cosmetics.
  4. Environmental and Water Treatment: It is used to adjust the pH of wastewater, precipitate and remove heavy metal ions from water, assist in the degradation of organic pollutants, and purify industrial effluent.
  5. Industrial Material Additives: It is used as anti-corrosion and weather-resistant additives in coatings, and as synergistic flame retardants for polymers; can be used in the manufacture of zinc batteries and materials for electronic sensor components.
