Product Description

transparent glass-ceramics is a new transparent functional material contains crystal and residual glass phase after substrate glass heat treatment. it is of better optical stability, thermal stability and mechanical property. because of the ultra low thermal expansion, transparent glass-ceramics is not influenced by high temperature, or the change and difference of temperature. it is widely used in mechanical engineering technology, electric power engineering, electronic technology and optical field, etc. basic properties 1.more stable chemical properties: anti-hydrating (hydration resistance), cation exchange resistance 2.higher mechanical strength 3.better electrical properties: minimum dielectric loss 4.excellent thermal property: low thermal expansion coefficient, good reting stability, high melting temperature applications i.mechanical engineering technology 1.mechanical bearing: high surface accuracy 2.used in bearings, valves, pipeline for gas and liquid of strong erosion 3.hole disc of heat exchanger ii.electric power engineering and electronic technology 1.high-frequency insulation and high voltage-insulation casing materials 2.prefabricated circuit in electronic technology, including multilayer circuit board 3.photoelectric material iii.optical field 1.excitation device components 2.giant astronomical telescope glass substrate 3.aerospaceplane antenna radome
