Product Description Glass-ceramics with most outstanding feature is the use of standard metal tools and equipment for milling, planing, grinding, drilling, sawing and tapping. Is the general 95 porcelain, silicon nitride porcelain and other insulating materials can not be compared. Glass-ceramics have similar processing properties as cast iron. It can be used to produce various products with complicated shape and high precision. Although glass-ceramics are brittle and hard materials, as long as the process route and clamping method are determined reasonably, the machining method is paid attention to and the cutting parameters are accurately selected, the tolerance grade can be controlled in IT7 grade and the finish can reach 0.5 μm in general equipment. Machining accuracy controlled at 0.005mm is perfectly feasible. The application of glass-ceramic ceramics can meet the requirements of high precision technology because of its excellent comprehensive properties, and it can greatly shorten the development period without mould design and manufacture. It can accelerate the progress of engineering and save the cost of research and development. It is especially suitable for automobiles. Military, aerospace, precision instruments, medical equipment, electrical vacuum devices, electron beam exposure machine, textile machinery, sensors, mass spectrometers and energy spectrometers and other instruments are widely used. For some thin-walled coil skeleton, insulation support of precision instruments and devices with complicated shape and other precision requirements, glass-ceramic ceramics are more suitable, and they can be machined into arbitrary shapes. It has higher strength than boron nitride. Low gas rate, temperature resistance than PTFE, no deformation, no deterioration, durable, better processing than alumina porcelain, short production cycle, high qualified rate, designers can make the required size of the products. The machinable ceramics have excellent thermal shock resistance, from 800 oC to 0 oC without breaking, 200 oC to 0 oC strength does not change. Due to its excellent properties, machinable ceramics have been widely used in the fields of aviation, aerospace, electronic substrate, high temperature insulation skeleton, ion plating, vacuum coating, ion microscope, ion accelerator, laser and medical equipment.Glass Ceramics PropertiesColorWhiteDensity2.7g/cm3Compressive Strength488MPaBending Strength108MPaThermal Conductivity1.68 W/m.KThermal expansion coefficient 8.6×10-6 K-1Application Tem(Max)800oCVolume resistivity1014Ω.cmDielectric constant6.5@1Hz Hardness(HRC)40
