Production and Processing of Technical Ceramics
Technical ceramics, also known as #engineering ceramics, #advanced ceramics, or #fine ceramics, are high-performance materials widely used in #semiconductor components, #precision components, and other demanding fields. These materials possess excellent physical and chemical properties, such as high hardness, high-temperature resistance, chemical corrosion resistance, and outstanding electrical insulation, making them a top choice for many cutting-edge industries.

Material Categories of Technical Ceramics
Technical ceramics can be divided into the following three main material categories:
- Oxide Ceramics
Common materials include alumina, zirconia, and beryllia. These materials exhibit excellent high-temperature resistance, making them particularly suitable for electrical insulation components in #semiconductor components or high-temperature parts of #precision components. - Non-Oxide Ceramics
Primarily include carbides (such as silicon carbide), nitrides, and borides. These materials feature extremely high hardness and wear resistance, commonly used in #ceramic machining for parts that endure extreme conditions, such as jet engine turbine blade coatings and missile nose cones. - Composite Ceramics
By reinforcing with particles or fibers, oxides are combined with non-oxides to enhance the comprehensive performance of materials. These ceramics play a significant role in high-performance applications of #engineering plastic processing.
Application Scenarios of Technical Ceramics
Technical ceramics are widely used in the production of the following parts and equipment:
- Gas burner nozzles
- Ballistic protection plates
- Nuclear fuel uranium oxide pellets
- Biomedical implants
- Jet engine turbine blade coatings
- Ceramic disc brakes
- Missile nose cones
- Thermal insulation tiles for spacecraft
CNC Machining and Technical Ceramics
Compared to metals and #engineering plastics, the machining of technical ceramics is more challenging. However, CNC technology provides a stable and efficient solution. Using conventional machine tools or specialized equipment for #ceramic machining, the following operations can be achieved:
- Sawing and Drilling: Suitable for rough machining and shape cutting of high-hardness ceramics.
- Milling and Turning: Used for detailed shaping of #precision components, especially for producing small parts and prototype verification.
- High-Precision Measurement and Control: CNC machining combined with precision measurement tools ensures each part meets strict tolerance requirements.
Special machinable ceramics (such as Macor® and boron nitride) with relatively lower machining hardness are particularly suitable for CNC engineers to quickly produce prototypes and small-batch production in conventional machine shops.
High-Performance Material Supply
In the processing of technical ceramics, selecting the right material is crucial. #Semiconductor components or other high-performance applications often opt for high-performance ceramics such as Macor®, Mycalex®, and boron nitride, supplied by specialized vendors (e.g., Professional Plastics) to meet various engineering needs.
Conclusion
Due to their unique properties, technical ceramics have become essential materials in the fields of #CNC machining and #ceramic machining. From #precision components to #semiconductor components, CNC engineers continue to push the boundaries of technical ceramic applications by leveraging innovative machining techniques and the selection of high-performance materials to meet stringent industry demands.
