The design idea of FCXG-96-14Q functional material sample preparation furnace is based on the experience of industrial furnace production process, which greatly reduces the sintering difference between experimental furnace and industrial furnace, and can provide reliable mass production process data for large-scale production line exploration. The production capacity of a single furnace can reach 30-500 kilograms, making it the preferred furnace type for ceramic powder material companies to submit samples for sintering. Its furnace size is 900×800×250mm.
