1500°C Tube Furnace
This tubular furnace can reach a maximum temperature of 1500°C. It features a double-shell structure and an air-cooling system. The furnace chamber is constructed of high-purity alumina fiber to minimize energy loss. The inner chamber surface is coated with a high-temperature alumina coating, which improves reflectivity and heating efficiency, extending the instrument's lifespan. It also includes overheat and burnout protection. The furnace offers advantages such as a balanced temperature field, low surface temperature, fast temperature ramp rates, and energy efficiency. It is ideal for universities, research institutes, and industrial and mining enterprises for sintering or annealing new material samples (under vacuum or inert gas protection).

A vacuum furnace is a high-tech industrial oven used for heat treatment processes, primarily in the manufacturing and processing of metals, ceramics, and other materials. The furnace operates in a controlled vacuum environment, meaning that the air is removed from the chamber, creating a low-pressure atmosphere. This unique condition allows for specific and often superior material properties to be achieved during the heating process. Let’s dive deeper into the purpose of a vacuum furnace and why...
