Firing

Firing is an important process in surface technology that is often used in the production of ceramic, glazed and porcelain-like surfaces. In this process, the material is exposed to a high temperature, which causes chemical and physical changes in the surface layer of the material.

Various effects can occur during the firing process, depending on the specific properties of the starting material and the desired results. The most common effects include:

- Sintering: In ceramic materials, firing results in sintering, whereby the particles of the material are bonded together under high temperatures to form a dense and solid structure.

- Glazing: In the ceramics and glass industry, firing is used to melt glazes and apply them to the surface of the material. This creates a smooth, shiny and often colored surface.

- Chemical reactions: Under high temperatures, chemical reactions can occur between the components of the material, which can lead to changes in color, texture and other properties.

- Removal of impurities: Firing can also serve to remove impurities and organic residues from the material, cleaning and improving the surface.

Overall, firing is a crucial step in surface engineering that helps to achieve the desired results.
