Here are some of the applications of magnesium chloride in ceramic industries:

1. Binder: Magnesium chloride can be used as a binder in the ceramic industry. It is often used as a binder for refractory materials, such as bricks and tiles, to improve their strength and durability.

2. Drying agent: Magnesium chloride can be used as a drying agent in ceramic production. It is often used to dry and harden ceramic products during the firing process.

3. Flux Magnesium chloride can be used as a flux in ceramic production. It helps to lower the melting point of ceramic materials and can promote the formation of glassy phases in the ceramic.

4. Additive: Magnesium chloride can be used as an additive in ceramic production. It can be added to ceramic glazes and body formulations to improve their properties, such as hardness, durability, and color.

5. Catalyst: Magnesium chloride can be used as a catalyst in ceramic production. It can help to promote the formation of certain crystal structures in the ceramic and can improve the efficiency of the firing process.
