Choosing a High-Temperature Muffle Furnace

What is a Muffle Furnace?

A Muffle furnace allows rapid high-temperature heating, recovery, and cooling in self-contained, energy-efficient cabinets. A muffle furnace separates the object to be heated from all byproducts of combustion from the heat source. In modern electrical furnaces, a radiation or convection energy applies heat to a chamber using a high-temperature heating coil inside insulated material. The insulating material effectively acts as a muffle, preventing heat from escaping.

Common Muffle Furnace Uses

Additionally, advances in materials for heating elements such as the molybdenum disilicide can produce working temperatures up to 1,800 degrees Celsius (3,272 degrees Fahrenheit). This high-temperature facilitates more sophisticated metallurgical applications like debinding, sintering, and end to end processes in metal injection molding.

Applications Using Muffle Furnaces

Muffle furnaces now use technology and design to achieve greater control of temperature uniformity and isolate heated materials from combustion contaminants. This makes muffle furnaces ideal for ashing samples, heat-treating applications, and materials research.

Industrial manufacturers or laboratory environments commonly use muffle furnaces for high-temperature applications. These applications include:
