Using an oxidized ceramic material (such as zirconia, alumina, etc.) for 3D printing, the green body samples are sintered in a 1700°C muffle furnace to obtain the final dense ceramic components. The 1700°C high-value box-type experimental electric furnace uses high-quality silicon-molybdenum rods as heating elements, adopts an intelligent temperature control system with silicon-controlled rectifier (SCR) control, ensuring high temperature control accuracy. The furnace chamber is constructed using a high-quality 1700-type alumina polycrystalline fiber inorganic material, formed by vacuum adsorption with Japanese technology, in a modular assembly structure, ensuring long-term use without deformation or collapse. The furnace body features a double-layer shell with an air-cooling system, effectively maintaining the surface temperature of the outer shell.
