Product Specification

Magnesium Oxide Application areas

It is used to determine sulfur and pyrite in coal and sulfur and arsenic in steel. It is used as a standard for white pigments. Light magnesium oxide is mainly used as a raw material for the preparation of ceramics, enamel, refractory crucibles and refractory bricks. It is also used as a polishing agent, adhesive, coating, and paper filler, and a promoter and activator for chloroprene rubber and fluororubber. After mixing with solutions such as magnesium chloride, it can be made into magnesium oxide water. It is used as an antacid and laxative in medicine, and is used for gastric acid hyperacidity and duodenal ulcers. It is used as a catalyst and a raw material for the manufacture of magnesium salts in the chemical industry. It is also used in the manufacture of glass, dye residue, phenolic plastics, etc. Heavy magnesium oxide is used for firing powder grinding and half-rollers in the rice milling industry. It is used in the construction industry to manufacture artificial chemical floors, artificial marble heat-resistant boards, sound insulation boards, and plastics industries as fillers. It can also be used to produce other magnesium salts.
One of the main uses of magnesium oxide is as a flame retardant. Traditional flame retardant materials widely use flame retardant mixtures composed of halogen-containing polymers or halogen-containing flame retardants. However, once a fire occurs, due to thermal decomposition and combustion, a large amount of smoke and toxic corrosive gases will be produced, which will hinder firefighting and personnel evacuation, and corrode instruments and equipment. In particular, people have found that more than 80% of deaths in fires are caused by thick smoke and toxic gases produced by materials. Therefore, in addition to flame retardant efficiency, low smoke and low toxicity are also essential indicators for flame retardants. The development of China's flame retardant industry is extremely unbalanced, with chlorine-based flame retardants accounting for a large proportion, ranking first among all flame retardants, among which chlorinated paraffin occupies a monopoly position. However, chlorine-based flame retardants release toxic gases when they act, which is far from the non-toxic and efficient pursuit of modern life. Therefore, in order to comply with the development trend of low smoke, low toxicity and pollution-free flame retardants in the world, the development, production and application of magnesium oxide flame retardants are imperative.

Specifications

Medical grade

Application areas: In the biopharmaceutical field, medical grade magnesium oxide can be used as an antacid, adsorbent, desulfurizer, lead removal agent, complexing filter aid, and pH regulator. It is used as an antacid and laxative in medicine to inhibit and relieve excessive gastric acid and treat gastric ulcers and duodenal ulcers. It has a strong, slow and lasting effect in neutralizing gastric acid and does not produce carbon dioxide.

Silicon steel grade

Application areas: Silicon steel grade magnesium oxide has good magnetic conductivity (i.e., it has a large positive magnetic susceptibility) and excellent insulation properties (i.e., the electrical conductivity can be as low as 10-14us/cm dense state). It can form a good insulating layer and magnetic conductive medium on the surface of silicon steel sheets to inhibit and overcome the eddy current and skin effect loss (referred to as iron loss) of the silicon steel core in the transformer. It improves the insulation performance of silicon steel sheets and is used as a high-temperature annealing isolator. It can also be used as ceramic materials, electronic materials, chemical raw materials, adhesives, additives, etc. It is used in silicon steel as a dephosphorizing agent, desulfurizing agent, and insulating coating generator.

Production Techniques

Magnesium oxide can be produced through various methods, including the carbonation process, calcination of magnesium hydroxide, soda ash process, and ammonium bicarbonate process. The choice of method often depends on the specific needs and characteristics of downstream industries. For example, the carbonation process can produce lightweight magnesium oxide, while the calcination of magnesium hydroxide can produce high-purity magnesium oxide.

Theory (Background)

Magnesium oxide consists of Mg²⁺ ions and O²⁻ ions bound together through ionic bonds to form a crystal lattice. At high temperatures, magnesium oxide exhibits excellent physical and chemical stability, making it a model system for studying crystal vibration characteristics. Additionally, magnesium oxide is widely regarded as the most effective metal stabilizer compared to silicate cement, lime, and others due to its superior buffering capacity, cost-effectiveness, and ease/safety of operation.

Services

Magnesium oxide enterprises should establish an application technology department with professional technical service personnel. These personnel should possess extensive knowledge and experience in production processes, technology, and magnesium oxide applications, enabling them to provide professional technical support and solutions to customers.

Packaging and Storage

Magnesium oxide should be stored in a cool, well-ventilated warehouse, avoiding direct sunlight and high temperatures. The warehouse should be kept away from fire sources and heat to prevent magnesium oxide from undergoing chemical reactions or fires due to high temperatures. The packaging of magnesium oxide should be intact to prevent leakage, damage, or dropping during transportation. According to the HG/T 2573-2012 standard, the packaging of industrial light magnesium oxide must comply with specific regulations.

Preventive Measures

1. Industrial Protection: Operators should wear appropriate personal protective equipment, such as dust masks, chemical safety goggles, breathable work clothes, and rubber gloves, during industrial use.
2. Medical Monitoring: When using magnesium oxide preparations in the medical field, they should be used as prescribed by a doctor to avoid long-term or excessive use, which may cause harm to the human body.
3. Environmental Monitoring: During storage and transportation, clear emergency response plans should be in place to address potential leaks or other emergencies.
