【Abstract】 Polycrystalline black ceramics plaster for infrared heating is a newly developed product in Shanghai Institute of Ceramics. The plaster can withstand high temperature up to 1790°C and its normal total emissivity is more than 0. 9. It can be used as inner layer on the wall of furnaces and stoves to protect refractory bricks from action and corrosion of the high temperature gases in the combustion chamber of furnaces. The plaster efficiently improves lifetime and thermal efficiency by saving energy of furnaces as it has been experienced in some metallurgical and petroleum works such as heating furnaces,annealing ovens and boilers.更多还原
