Product Description

Product Description

Basic zinc carbonate is a remarkable inorganic compound characterized by its chemical formula Zn2(OH)2CO3, presenting as a pristine white, fine, and amorphous powder. This substance is both odorless and tasteless, boasting insolubility in both water and alcohol, while being slightly soluble in certain conditions, and readily dissolvable in dilute acids. It serves a versatile role across various industries, finding application in light astringents, latex products, skin protectants, rayon production, as well as in desulfurization agents. Moreover, it is a valuable component in analytical reagents, the pharmaceutical industry, and as a beneficial feed additive.

1. Properties: Exhibits as a white, fine, and amorphous powder, maintaining its odorless and tasteless nature.
2. Solubility: Demonstrates insolubility in water and alcohol, while being slightly soluble in specified circumstances. It is also known to dissolve in dilute acid successfully.
3. Stability: Remains stable at ambient room temperature and under standard pressure conditions.
Preparation Method
The preparation of basic zinc carbonate involves using the mother liquor derived from zinc oxide ore powder as the raw material. This liquor is heated to a precise temperature range of 78-85°C. During this process, solid ammonium carbonate is introduced under consistent stirring, with the pH level of the reactant meticulously controlled between 6.0 and 6.5. The reaction is carefully monitored and terminated at the optimal point to successfully yield basic zinc carbonate.
Storage Method

To ensure product integrity, store in a cool, ventilated, and dry warehouse. It is imperative not to store or transport alongside acidic or alkaline items. The product should be kept away from moisture. During transportation, it is crucial to avoid exposure to rain, moisture, direct sunlight, and heat. In the unfortunate event of a fire, extinguish using water, sand, or a suitable fire extinguisher.
