As an accelerator and activator for neoprene and fluororubber: Can be used as a filler for adhesives, paints, and paper. Also used in the manufacture of ceramics, enamel, refractory materials, and magnesia cement.

In medicine (again): Used as an antacid and laxative. Specifically as an antacid for gastric and duodenal ulcers.

In refractories, enamel, abrasives, adhesives, and paints:

Magnesium oxide crystals: Used as substrates for various thin-film formations, protective film materials for PDPs (Plasma Display Panels), optical materials, high-temperature materials, and window materials.

High-purity magnesium oxide powder: Used in PDP protective film materials, PDP phosphor pastes, high-purity ceramic materials, glass materials, coating materials, electronic insulating materials, and various additives.

Properties and other uses: Depending on the preparation method, it can be classified as light or heavy magnesium oxide. It has strong refraction in the visible and near-ultraviolet light range. When exposed to air, it readily absorbs moisture and carbon dioxide, gradually becoming basic magnesium carbonate, with light magnesium oxide reacting faster than heavy. It combines with water to form magnesium hydroxide, exhibiting a slightly alkaline reaction, with a saturated aqueous solution pH of 10.3. It is used in the determination of sulfur and pyrite in coal, and sulfur and arsenic in steel. It serves as a standard for white pigments.

In ceramics and refractories: Used in the manufacture of ceramics, enamel, refractory crucibles, and refractory bricks.

As an abrasive, binder, and filler: Used as an abrasive, binder, filler for paints and paper, accelerator and activator for neoprene and fluororubber. When mixed with solutions such as magnesium chloride, it can produce magnesia cement.

In medicine (again): Used as an antacid and laxative for hyperacidity, gastric, and duodenal ulcers.

In other industries: Also used in glass, dyes, phenolic plastics, etc.

Food-grade uses: Used as a decolorizing agent in sugar refining and a pH regulator in ice cream powder.

In paper, chemicals, construction, rubber, ceramics, animal husbandry, and magnesia production.

In rice milling: Used for firing sand rollers and sand hullers.

In construction: Used in artificial seamless floors, artificial marble, heat insulation boards, and sound insulation boards.

In chemicals, rubber, plastics, and steel ball polishing.

Widely used as a high-temperature heat-resistant material:

In ceramics: Used as a raw material for translucent ceramic crucibles, substrates, etc.

In electronic and electrical materials: Used as a filler for magnetic devices, insulating materials, and various carriers.

As a ceramic substrate: Has twice the thermal conductivity of alumina and only 1/10 the electrolyte loss of alumina.

Also used as a filler in heat-resistant coatings.
