A high-temperature furnace is a versatile piece of equipment used in various industrial and laboratory applications, capable of reaching extreme temperatures depending on its design and purpose. The temperature range of a high-temperature furnace varies significantly based on its type and application. For instance, muffle furnaces can reach up to 1800°C, while other types like box-type or programmable high-temperature furnaces typically operate between 1350°C and 1550°C. Preheating furnaces, on the other hand, may achieve maximum temperatures of around 1200°C. The specific temperature range is influenced by factors such as the furnace's design, heating elements, and intended use, making it essential to select the appropriate furnace for specific applications like sintering, annealing, or material testing.
