Sodium titanate and potassium titanate are two common titanate compounds that belong to electrolytes because they can dissolve in water and conduct electricity. Both of these compounds have a wide range of applications, but there are still some differences between them.

Sodium titanate is a colorless crystal with the chemical formula Na2TiO3. Its molecular weight is 159.88 g/mol, its specific gravity is 3.78 g/cm ³, and its melting point is 1350 ℃. It is a weakly alkaline compound. It can be used together with sodium tungstate as a pollution-free and environmentally friendly desulfurizer, and can be used to prepare new catalysts. Sodium titanate can also be used in industry for the preparation of materials, fine chemicals, and metal surface treatment agents.

Potassium titanate is a white crystal with the chemical formula K2TiO3. Its molecular weight is 230.93g/mol, its specific gravity is 3.18g/cm ³, and its melting point is 860-870 ℃. It is an alkaline compound. Potassium titanate can be used in the manufacturing of high-energy batteries, glass and capacitor dielectrics, and can also be used as a positive electrode material, efficient catalyst, anti-corrosion coating, etc. for lithium containing batteries.

In industry, sodium titanate and potassium titanate are widely used. Below is a brief introduction to their applications in certain specific fields.

1. Catalyst

Sodium titanate, as an organic catalyst, is widely used due to its excellent catalytic activity and stability, such as increasing the octane number of unleaded gasoline, serving as a catalyst in the preparation of soaked rubber, and as a catalyst for hydrogenation reactions; Potassium titanate catalyst can be widely used in the adsorption and desorption of various gases.

2. Surface modification

Sodium titanate has great application prospects in metal surface treatment, such as surface treatment of difficult to treat metals (stainless steel, aluminum profiles), improving the performance of certain space materials, etc; Potassium titanate can be used to improve the dielectric and heat resistance of fibers, wood, and rubber materials.

3. Auxiliary flux

Sodium titanate can be used as a flux in iron carbon alloys and stainless steel, while potassium titanate can also be used as a flux in aluminum alloys.

4. Positive electrode material of battery

Potassium titanate is a high-performance electrochemical material that can be used to make positive electrode materials for high-energy batteries and capacitor dielectrics.

5. Anti corrosion materials

Sodium titanate and potassium titanate are both excellent anti-corrosion materials that can be used in metal anti-corrosion coatings.

6. Preparation of microporous carrier

Potassium titanate can be used as a microporous carrier for the preparation of dyes, pollution control, and chemical catalysis.

From the above application scope, although sodium titanate and potassium titanate have many common application areas, the two types of titanate compounds still have differences in details. Overall, potassium titanate has a wider range of applications and higher functional value.
