precision mica glass ceramic insulating knob block
Reputation depends on quality, quality comes from Hard!
Machinable Glass Ceramic:
The molten glass can be obtained in a uniform state, and the crystallization process can be strictly controlled, so that a uniform structure having extremely fine crystal grains and no defects such as gap can be obtained, and this structure makes the glass ceramic have better strength than general ceramics and glass. , wear resistance, electrical insulation and hardness. Some of the main functional materials studied today are translucent glass ceramics, ferroelectric and ferromagnetic glass ceramics, transparent glass ceramics doped with Cr3+ plasma, and glass ceramics for electronic devices and their sealing, used as catalyst carriers and sensors. Porous doped glass ceramics and the like. However, when the amount of functional crystals is insufficient, the performance will cause a "dilution" effect. Although the material has certain functional properties, the performance index is poor and cannot meet the application requirements. Therefore, how to improve the crystallization rate of functional crystals and make the material as single phase as possible or contain the least heterophase is the focus of research in this kind of materials.
Good insulativity, high temperature(800°), good machinable property, can be made of rod and plate in short time.
