high tolerance machinable mica macor Glass Ceramic Parts
Reputation depends on quality, quality comes from Hard!
Macor Glass Machinable Glass Ceramic:
application
(1) β-spodumene glass-ceramics and carbon fiber composites: strong toughening effect, new materials in aerospace.
(2) Oxygen-nitrogen glass-ceramics: Direct microcrystallization can be performed without radiation or addition of crystal nuclei, which lowers the sintering temperature of the Silicon Nitride crystal and maintains a high-strength β-silicon nitride structure.
(3) Cleaved mica glass-ceramics: layered structure, good electrical insulation and heat resistance (electronic insulating materials)
Production Process
The preparation method of the glass ceramics includes a whole crystallizing method (melting method), a sintering method, a sol-gel method, etc., and the methods currently applied industrially in China are the former two.
(1) Overall crystallization method
1) Forming crystal nucleus in the glass by adding crystal nucleating agent or ultraviolet irradiation
2) After the heat treatment, the crystal nucleus grows up, and other production processes are the same as ordinary glass.
Process: melting and forming, pre-crystallization processing, crystallization heat treatment, processing of glass-ceramics
At present, it is widely used in the cooker of the induction cooker. The concave type microcrystalline glass refers to the glass ceramic which has a concave shape and is similar to the current state of the pot. The main use of the glass-ceramic plate is currently mainly used in high-power commercial induction cookers and household induction cookers. With the increase in gas prices, the cost of the catering industry, and the perception of cooking without open flames, the number of household cookers has increased. Sales of concave glass-ceramics have also increased accordingly.
properties:
Good insulativity, high temperature(800°), good machinable property, can be made of rod and plate in short time.
