Product Overview

W&Q's Magnesium Oxide (molecular formula: MgO), also known as magnesia, is a high-purity inorganic compound available in white crystalline powder or granular form. It features high melting point, excellent chemical stability, non-toxicity, and good alkaline properties. Magnesium, as an essential macroelement, plays a pivotal role in human and animal physiology, plant growth, and industrial production.W&Q manufactures magnesium oxide in strict compliance with GMP and ISO standards, utilizing advanced calcination and purification processes to ensure consistent purity, controlled particle size, and low heavy metal content. Our product is widely applied in animal nutrition, pharmaceutical formulations, food additives, construction materials, and industrial catalysts, providing a reliable magnesium source and functional additive for global customers.

Product Benefits

1. Animal Nutrition & Physiological Regulation: It provides bioavailable magnesium for livestock and poultry, supporting bone formation, nerve conduction, muscle contraction, and electrolyte balance. It helps prevent magnesium deficiency-related issues such as tetany, poor growth, and reduced reproductive performance, improving feed conversion rates and breeding efficiency. W&Q’s magnesium oxide has optimal alkalinity, which can adjust the pH value of animal digestive tracts and promote nutrient absorption.

2. Pharmaceutical & Food Applications: In pharmaceuticals, it acts as an antacid and laxative, effectively neutralizing gastric acid to relieve indigestion and heartburn, and regulating intestinal peristalsis. In food industry, it is used as a magnesium fortifier, pH adjuster, and anti-caking agent, suitable for dairy products, baked goods, and beverages. It is non-toxic and has good biocompatibility, meeting food-grade safety requirements.

3. Industrial Functional Properties: In construction, it is a key raw material for refractory bricks, insulation materials, and cement additives, enhancing product hardness and high-temperature resistance. In chemical industry, it serves as a catalyst, adsorbent, and neutralizing agent, with stable performance and wide applicability. W&Q offers customized particle size products to meet different industrial process needs.

4. Plant Growth Support: As a magnesium supplement for crops, it promotes chlorophyll synthesis and photosynthesis, improving crop yield and quality. It also adjusts soil pH, alleviating soil acidification and enhancing nutrient availability, suitable for magnesium-deficient soils and crops such as fruits, vegetables, and grains.

Usage

- Animal Nutrition: Mixed into livestock and poultry feed. Recommended dosage varies by species and growth stage: 0.2-0.5% for poultry feed, 0.3-0.8% for swine feed, and 0.5-1.0% for ruminant feed (especially dairy cows to prevent milk fever). W&Q provides tailored dosage guidance based on breeding purposes.

- Pharmaceuticals & Food: In pharmaceuticals, oral dosage for adults is 200-400 mg per time, 3 times a day (as antacid). In food industry, the addition amount is 0.1-0.5% depending on product types, following national food additive standards.

- Industrial Applications: For refractory materials, the addition ratio is 20-50%; for cement additives, 1-5%; for catalysts, dosage is determined by reaction process. W&Q offers technical support for industrial application optimization.

- Agricultural Use: Used as soil amendment or foliar fertilizer. For soil application, dosage is 500-1000 kg/ha; for foliar spray, dilute to a 0.5-1.0% solution and apply during crop growth period.

Storage: Store in a dry, cool, and well-ventilated warehouse, away from moisture, direct sunlight, acids, and water. Keep sealed tightly to prevent moisture absorption and caking. Shelf life is 24 months under proper storage conditions.

FAQ

Q1: What are the differences between light and heavy magnesium oxide?

A1: Light magnesium oxide has low bulk density (0.1-0.3 g/cm³), large specific surface area, and good activity, suitable for pharmaceuticals, food, and catalysts. Heavy magnesium oxide has high bulk density (0.5-1.0 g/cm³) and high hardness, suitable for refractory materials and construction. W&Q provides both types to meet diverse application needs.

Q2: Is magnesium oxide safe for long-term use?

A2: Magnesium is an essential element for the human body, and magnesium oxide is safe when used within recommended dosages. Long-term excessive intake may cause diarrhea or electrolyte imbalance. W&Q’s products are formulated to meet safety standards, and adherence to dosage guidelines is advised.

Q3: Can it be mixed with other additives?

A3: It has good compatibility with most additives, but avoid mixing with strong acids (which may cause exothermic reactions). For large-scale mixing in feed or industrial applications, W&Q recommends conducting a small-scale compatibility test first.

Q4: Does it meet international quality standards?

A4: Yes. W&Q’s magnesium oxide complies with global standards such as USP, BP, FCC, and GB/T 9857-2017, with heavy metal content (Pb, Cd, As) below 5 ppm, fully meeting food, feed, pharmaceutical, and industrial grade requirements.
