【Product name】: zinc carbonate basic industrial grade/cosmetics grade/feed grade

【Chemical formula】: ZnCO3.2Zn(OH)2.H2O

【CAS】: 3486-35-9

【Application】:

1. It’s specially used in transparent rubber products and foaming agent EVA because of its refractive index similar to rubber.

2. Special basic zinc carbonate can be used as a skin protective agent in medical applications.

3. In the industry, it’s used as light astringent and latex products, also is compound of calamine lotion. It can be used as main raw material of rayon production, desulfurizing agent in chemical fertilizer industry and catalyst production.

4. In the oil drilling, basic zinc carbonate reacts with H2S to form ZnS which is stable and insoluble, and that the mud slurry performance is not affected after adding basic zinc carbonate into the mud. So it can eliminate the pollution and corrosion of H2S effectively, also can be used as corrosion inhibitor and sulfur removal agent to process H2S in oil and gas wells.

5. Zinc carbonate can also be widely applied to rubber soles, rubber-plastic product accessories, pipe fittings ,rubber plates, motorbike tires, belts, rubber band, ZPT, desulfurizer agent, zinc stearate, etc.

Q1: What is feed-grade zinc carbonate used for?

A1: Feed-grade zinc carbonate is used as a nutritional supplement in animal feed. Zinc is an essential mineral required for various physiological functions in animals, including growth, immunity, and reproduction. Feed-grade zinc carbonate provides a bioavailable source of zinc, which helps prevent or treat zinc deficiency in livestock and poultry. It is commonly added to animal feed formulations to ensure animals receive adequate levels of zinc in their diet, promoting overall health, growth performance, and disease resistance.

Q2: What is the difference between feed-grade zinc oxide and zinc carbonate?

A2: Feed-grade zinc oxide and zinc carbonate are both sources of supplemental zinc used in animal feed, but they differ in their chemical composition and properties:

Chemical Composition: Zinc oxide consists of zinc and oxygen atoms (ZnO), while zinc carbonate contains zinc, carbon, and oxygen atoms (ZnCO3).

Solubility: Zinc oxide is relatively insoluble in water, which means it releases zinc ions slowly in the digestive tract, providing sustained supplementation over time. In contrast, zinc carbonate is more soluble in acidic environments, allowing for faster release of zinc ions in the stomach.

Bioavailability: Zinc oxide is less bioavailable compared to zinc carbonate because of its lower solubility. However, some animal species, such as pigs, can efficiently utilize zinc from zinc oxide due to their ability to produce stomach acid. Zinc carbonate, being more soluble, may offer higher bioavailability, particularly in species with less efficient zinc absorption.

Formulation: Due to its insolubility, zinc oxide is commonly used in premixes and compound feeds where sustained release of zinc is desired. Zinc carbonate may be preferred in situations where rapid zinc supplementation is required or where animals have difficulty absorbing zinc from other sources.
