Read： 1346 Time：13months ago Source：Transform the World with Simplicity

Sodium oxide is an important inorganic chemical raw material, which is widely used in the field of chemical production. This article will detail the nature and use of sodium oxide.

1. the nature of sodium oxide

sodium oxide (Na2O) is a white solid, with strong alkaline. It is readily soluble in water, producing sodium hydroxide (NaOH). Sodium oxide easily absorbs moisture and carbon dioxide in the air to produce sodium carbonate (Na2CO3).

sodium oxide has high chemical activity and can react with many acidic oxides and acidic salts to generate corresponding salts. In addition, sodium oxide has good thermal stability and can be stable at high temperatures.

2. the use of sodium oxide

1. the preparation of sodium hydroxide

sodium oxide is dissolved in water to generate sodium hydroxide, so it is commonly used in the preparation of sodium hydroxide. Sodium hydroxide is a strong alkali, widely used in chemical industry, light industry, textile, printing and dyeing and other industrial fields.

2. as a desiccant

sodium oxide has strong water absorption, can be used as a desiccant for absorbing gas or liquid moisture.

3. preparation of other chemicals

sodium oxide can also be used for the preparation of other chemicals, such as sodium nitrite, sodium peroxide and so on. In addition, sodium oxide can also be used for the preparation of metallic sodium and as a raw material for the preparation of other sodium salts.

4. Used in glass, ceramics and other industries

sodium oxide as an important raw material for glass, ceramics and other industries, which can improve the strength and heat resistance of products.

In short, sodium oxide, as an important inorganic chemical raw material, has a wide range of applications in the field of chemical production raw materials. Understanding the properties and uses of sodium oxide will help to better apply it in actual production and improve production efficiency and product quality.
