  • Details
  • Parameter



Conductivity 180W/m.k One of the highest thermal conductivity materials

in metallic materials (7-10 times of alumina ceramic)。

Excellent mechanical properties, good processing, high precision, smooth

吉林快3开奖 surface, no microcracks, Bending, etc.Low dielectric constant and dielectric

loss, reliable electrical insulation performance.Non-toxic,High temperature

of 1800 degrees, oil resistant, chemical resistant, and similar to the thermal expansion coefficient of silicon,Without hygroscopic property, stable performance and high reliability in high temperature and high humidity.Along with the micro electric.The extensive development of the microelectronic equipment, the high thermal conductivity nitride ceramic film is widely valued and applied.
