Multiphase ceramics high-temperature electric heating film

Author:Ben Date:2011-1-19 21:42:02

Environment-friendly multiphase ceramics high-temperature electric heating film is a new subnanoscale electrothermal material,as is a application of crystal coordinate principle and electricity, calorifics,mechanics and optics principle of wemiconductive ceramics and membrane material.It is a composite material by the union of Micro scale electronic paste and nanoscale.subnanoscale multifunctional disperes phase.
