Overview of Glass-ceramics processing

Glass-ceramics processing is a new type of material that combines the properties of glass and ceramics. It has the homogeneity and transparency of glass and the high strength and temperature resistance of ceramics, and can be precisely molded by traditional machining means (e.g., turning, milling, drilling, etc.). Its microstructure consists of a glass phase and a tiny ceramic crystal phase, and its performance can be adjusted by composition design. It is widely used in electronic packaging, optical devices, aerospace and other fields, and shows unique advantages in the field of precision manufacturing and high-end technology.

Features of Glass-ceramics processing

In terms of processing performance, it breaks through the limitations of traditional ceramics that are difficult to be machined, and can be molded with high precision by turning, milling, drilling, and other conventional machining methods like metal, which can easily realize the processing of complex geometries, significantly reduce the processing difficulty and cost, and meet the needs of precision manufacturing.

Physical properties, machinable glass-ceramics, both the homogeneity of glass and ceramic, high strength, high hardness and good impact resistance, as well as excellent high-temperature performance, in a high-temperature environment to maintain stable physical and chemical properties, not easy to deformation or melting, a wide range of applications.

Chemical stability, processable glass ceramic acid and alkali corrosion resistance, in the harsh chemical environment, can still maintain stable performance, not easy to chemical reaction with other substances, suitable for use in special environments.

In addition, the microstructure of processable glass-ceramics consists of glass phases and uniformly distributed tiny ceramic crystal phases. By adjusting the composition and process, it is possible to flexibly control the performance, such as dielectric constant, coefficient of thermal expansion, etc., which can be customized according to different application scenarios. It has shown excellent comprehensive performance in the fields of electronic packaging, optical devices, aerospace and so on. It has provided an ideal choice of materials in the field of high-end technology.

5 FAQs of Glass-ceramics processing

Q1: How to solve the chipping problem in machinable glass-ceramics processing?

Chipping can be reduced by more than 60% by optimizing tools (e.g., diamond-coated tools), adopting a layered cutting strategy (depth of cut 0.05mm/layer), and improving equipment rigidity (e.g., dynamic balancing system for ceramic engraving and milling machines).

Q2: Are machinable glass-ceramics environmentally friendly?

Part of the processable glass ceramics can be prepared using fly ash, steel slag and other industrial wastes, reducing resource consumption and environmental pollution, while the material itself is non-aging, non-deformation, and highly chemical stability.

Q3: What are the advantages of processable glass ceramics compared with traditional ceramics?

Traditional ceramics need to be sintered and then processed with diamond tools, while machinable glass ceramics can be cut directly, reducing the processing cost by 30%-50%, and with better dimensional stability (coefficient of thermal expansion as low as 10^-6/°C), it is suitable for precision manufacturing.

Q4: How biocompatible is machinable glass-ceramic?

Processable glass ceramics are biocompatible and can be used to make artificial bone, dental implants, etc. The composition can be designed to match the mechanical properties and physiological compatibility of human tissues.

Q5: What is the future development trend of processable glass ceramics?

With the development of 5G, artificial intelligence and other technologies, the demand for processable glass ceramics in high-frequency electronic devices, precision optics and other fields will continue to grow. In addition, the application of laser processing technology (e.g., microporous manufacturing) and environmentally friendly formulations (industrial waste utilization) will become research hotspots!
