Funções e Aplicações

  1. 1:Refractories:One of the primary applications of magnesium oxide is in the production of refractory materials. It is used to manufacture refractory bricks, crucibles, and other high-temperature materials due to its resistance to extreme heat.

  2. 2:Magnesium Metal Production:Magnesium oxide is a key component in the production of magnesium metal. It is used as a raw material in the magnesium smelting process, where it is reduced to produce metallic magnesium.

  3. 3:Agriculture:It is used as a source of magnesium in fertilizers to correct magnesium deficiencies in soil, which can improve plant growth and crop yields.

  4. 4:Construction:Magnesium oxide is sometimes used as a construction material in the form of magnesium oxide boards or panels. These panels are lightweight, fire-resistant, and have good insulation properties.

  5. 5:Medical and Pharmaceutical:In the medical and pharmaceutical industries, magnesium oxide is used as an antacid to relieve symptoms of heartburn, acid indigestion, and upset stomach. It works by neutralizing excess stomach acid.

  6. 6:Environmental Remediation:It is used in environmental remediation processes to treat acidic soil and water, neutralizing harmful acidic substances.

  7. 7:Industrial Catalyst:Magnesium oxide is employed as a catalyst in various chemical reactions, particularly in the production of petrochemicals and biodiesel.

  8. 8:Tratamento de águas residuais:It is used to adjust the pH levels and remove impurities in wastewater treatment processes.

Precauções de manuseamento:

  • Magnesium oxide is generally considered safe to handle, but inhalation of fine dust should be avoided. Adequate ventilation and appropriate personal protective equipment, such as dust masks and safety goggles, should be used when handling fine powders.

Embalagem e armazenamento:

  • Magnesium oxide is typically available in bags or bulk containers. It should be stored in a dry place away from moisture to prevent clumping.

Conformidade Regulatória:

  • Ensure that magnesium oxide meets the relevant quality and safety standards depending on its intended application. In pharmaceutical applications, it must comply with pharmaceutical-grade requirements.

Informação do fornecedor:

  • Source magnesium oxide from reputable suppliers to ensure product quality and consistency, especially when used in critical applications.

The specific properties and uses of magnesium oxide may vary depending on the manufacturer and intended application. Always refer to the product's technical data sheet and consult with experts when using it in specialized applications.
