Product Description
Machinable Glass Ceramic has a continuous use temperature of 800ºC and a peak temperature of 1000ºC. Its coefficient of thermal expansion readily matches most metals and sealing glasses.It processes good machinability and can be lathed, milled, planed, ground, bored, incised and threaded. It also has the advantages of insulation, pore-free, high/low-temperature resistant, acid and alkali resistant and thermal impact resistant.Detail Description
Magnetic susceptibility ≤1.2×10-6
Dielectric constant 6~7
Breakdown voltage ≥15 KV/mm
Flexural strength ≥108Mpa
Fracture Modulus 15000bf/in2
Impact toughness ≥ 3.8 KJ/m2 Knoop
Hardness 176~343 kg/mm2
Volume density 2.5~2.8 g/cm3
Range of operating temperature -200~+1000ºC
Thermal expansion coefficient ≤94×10-7 /K
Thermal conductivity ≥ 1.7 W/m·K
Applications
It is widely used for nuclear, microwave high vacuum insulation, high precision magnetism-free skeleton for aeronautic and astronautic electrical devices, ultra-high voltage insulation for electric motors and structural parts at strong erosion environments. In terms of machinability, it can take place of aluminum oxide and boron nitride ceramics that are difficult to machine.
