The common method is to add carbon powder during the production process, causing some zirconia to turn into carbozirconia. There are also processes that add other colorants, and there are also processes that change the crystal structure of zirconia.

2. There is no distinction between good and bad colors. However, the processing technique for black blades involves an additional step compared to white ones, which results in a slightly higher price.

Are all zirconia ceramic knfe blades black ?

Zirconium oxide ceramic blades are not all black. White blades also exist.Zirconia ceramics come in various colors, and each color is closely related to its chemical composition and properties. The characteristics of different colored zirconia ceramics are as follows:

1. Zirconia ceramics:

 Black color is usually achieved through special processes (such as adding carbon powder or altering the crystal structure), while the white color is the natural color of zirconium oxide itself.

The reason for the color difference

1) The high purity chemical composition and good light transmittance make it appear white.

The white blades have not undergone special processing and retain the original white color of zirconium oxide.2) It has high hardness and high strength, and is often used to manufacture high-strength parts such as cutting tools and grinding tools.

 The black blades are made by adding carbon powder (such as carbozirconium) or using other colorants, as well as adjusting the crystal structure.

What are the differences between the black and white zirconia ceramic knives?

The commonly used zirconia ceramic knives are all made of zirconia. Zirconia originally has a white color.3) It has excellent wear resistance and corrosion resistance, and can be used to manufacture high-wear-resistant parts.

 However, the surface of the ceramic knife is matte, and the white blade appears less elegant than the black one. Therefore, special processes are used to make the ceramic black.4) It has high insulation properties and is suitable for manufacturing high-insulation parts such as electronic components.
