Blue zirconia ceramic is known for its exceptional performance characteristics:

● High hardness and high toughness, commonly used in the manufacture of high-strength and high-toughness parts;

●Excellent wear resistance and corrosion resistance, commonly used in the manufacture of high wear and corrosion-resistant parts;

●Good light transmittance and radiation resistance, commonly used in the manufacture of medical equipment and other high light transmittance and radiation resistance parts.


Difficulties in processing blue zirconia ceramics:

Due to the extremely high hardness of blue zirconia ceramics, conventional drilling and milling processes are difficult to achieve good machining results and require superhard grinding tools.

Secondly, the blue zirconia ceramics have higher toughness, the probability of problems such as small cutting angle, tool overheating and surface cracks is greater, and reasonable tool selection, cutting parameter control and cutting fluid cooling measures are required.

In addition, its machining accuracy requirements are higher, prone to poor surface quality, dimensional deviation and other problems, need to use such as high-precision CNC machining centres and optical measuring instruments and other advanced processing technology and equipment to ensure the processing quality and efficiency.

Therefore, the processing of blue zirconia ceramics has higher technical content and difficulty compared with ordinary white zirconia ceramics, requiring professional processing technology and equipment and skilled processing technicians.
