This is a large-diameter multi-zone tube furnace featuring a double-shell structure, with an inner silicon carbide (SiC) tube and an outer stainless steel tube. Inert gas is filled between the two layers, effectively preventing the gas from the inner tube from diffusing into the air.
The Tube Furnace with Silicon Carbide Tube from Across International is a high-performance heating solution designed for a wide range of thermal processing applications. Featuring a durable silicon carbide (SiC) heating element, this furnace delivers exceptional temperature uniformity, rapid heating rates, and long-lasting reliability, making it ideal for materials research, ceramics processing, and heat treatment. The robust construction ensures consistent performance even at extreme temperatures, while the precision temperature control system allows for accurate and repeatable results. Whether used in laboratories or industrial settings, this tube furnace offers a versatile and efficient solution for demanding thermal processes.
The chamber is made of high-quality alumina polycrystalline fiber.
The inner surface of the furnace chamber is coated with an imported high-temperature alumina coating (up to 1800°C), enhancing emissivity and ensuring a more uniform temperature field.
