The difference and connection between magnesium oxide and magnesium carbonate

Magnesium oxide(MgO)and magnesium carbonate(MgCO3)are two common magnesium containing compounds,which have significant differences and connections in multiple aspects.The following is a specific analysis

Magnesium oxide(MgO)and magnesium carbonate(MgCO3)are two common magnesium containing compounds,which have significant differences and connections in multiple aspects.The following is a specific analysis:

chemical property

Magnesium oxide:belongs to alkaline oxides,insoluble in water,but soluble in acids to form corresponding salts and water.

Magnesium carbonate:a weak acid salt,slightly soluble in cold water,soluble in acid and releases carbon dioxide.Heating to a certain temperature will decompose into magnesium oxide and carbon dioxide.

physical property

Magnesium oxide:usually a white or off white powdery solid with high density,hardness,and good thermal conductivity.

Magnesium carbonate:It is a white granular powder,odorless and tasteless,not easily decomposed at high temperatures,and has good stability.

Industrial applications

Magnesium oxide:mainly used in industrial products such as silicon steel,ceramics,optical glass,rubber products,and light calcium phosphate.

Magnesium carbonate:commonly used in fields such as medicine,rubber,and cosmetics.In the field of medicine,it can be used to prepare magnesium salt drugs;In the field of cosmetics,it can play a role in isolating ultraviolet rays;In the field of rubber,it can be used to increase the hardness and stability of products.

Product Features

Magnesium oxide:It is a white powder that is alkaline but insoluble in water.

Magnesium carbonate:It is a colorless and transparent crystalline substance that is alkaline,easily soluble in water,and slightly alkaline.

In summary,there are significant differences between magnesium oxide and magnesium carbonate in terms of chemical properties,physical properties,industrial applications,and product characteristics.However,both are important magnesium compounds that play irreplaceable roles in their respective application fields.
