  • Specification

1400C controlled Atmosphere furnace is designed for material synthesis under controlled inert gas Atmosphere up to 1400C. The furnace consists of high quality Alumina fiber brick and Sic heating element, as well as vacuum sealed steel case. 
It is an ideal tool for preparing new materials which requires a heat treatment under inert gas. .

Part 1

-- Protective Atmosphere Melting Furnace Structure

► High quality Alumina fiber inner insulator and double layer steel outer layer with air cooling fan to keep case temperature below 55C(energy saving 40% and weight lighter about 30% than old furnace).
► Double layers steel casing with fan cooling, to ensure the surface of furnace below 50C.
► Gas inlet and venting port are installed for using at oxygen or inert gas riched Atmospheres.
► Built in Pressure gauge, vacuum valves and two gas floameters.
-- Protective Atmosphere Melting Furnace Features
♦ High quality super Sic heating element serve as heating element and can be heated up to 1400C. 
♦ High purity and reflective Al2O3 ceramic fiber board with ZrO2 Liner coating for max energy saving.
♦ Energy saving 1500 grade fibrous alumina insulation.
♦ Double layer steel case with air cooling to ensure low surface temperature. 
♦ Effective heated chamber: 300x300x400mm. 
♦ Built in precision digital temperature controller is 30segments programmable to control heating rate, cooling rate and dwell time. 
♦ The furnace temperature is controlled by precision SCR (Silicon Controlled Rectifier) digital controller with accuracy +/-1C and 30segments programmable up to 1400C. 
-- Protective Atmosphere Melting Furnace Application
Vacuum Crucible Furnaces are widely used in the fields of metallurgy, ceramics, glass, machinery, analysis test, semiconductor, science & research and so on.
