A mortar is a kind of grinding vessel, used for grinding powder, with spout and pestles.

The specifications of the emulsion are generally measured in diameter, and different diameters of the emulsion are selected according to the needs.

The material of the emulsion is generally ceramic, but also corundum emulsion, agate emulsion, etc.

High Temperature Resistance

It has the characteristics of high melting and boiling point and can be used at high temperature without being affected.

Electrical Insulating

Insulator has high resistivity at room temperature. It can be used in equipment requiring insulation.
