When comparing an electric oven and a muffle furnace, it's important to understand their primary purposes and temperature capabilities.
4 Key Differences Between Electric Ovens and Muffle Furnaces
1. Purpose and Temperature Range
An electric oven is primarily used in kitchens for baking and roasting food.
It is typically made of brick or metal and designed for cooking large quantities of food at once.
Electric ovens operate at lower temperatures, commonly used for drying materials in sample preparation or for moisture content determinations.
On the other hand, a muffle furnace is a heating device used for high-temperature applications such as loss-on-ignition, ashing, or other material testing.
Muffle furnaces can reach much higher temperatures, with a maximum temperature of up to 1,473 K (1,200 °C; 2,192 °F).
2. Design and Construction
Electric ovens are built for kitchen use and feature racks, timers, and temperature controls specifically designed for cooking food.
Muffle furnaces, however, have a cylindrical chamber with sliding doors at both ends, allowing for easy access to the heated chamber.
3. Heat Transfer Mechanism
Electric ovens use convection heat to cook food, circulating hot air around the food.
Muffle furnaces provide radiant heat to the surrounding substances instead of convection, making them suitable for experimental research or heat treatment of materials at high temperatures.
4. Applications
Electric ovens are used for cooking food at lower temperatures.
Muffle furnaces are used for high-temperature material testing or heat treatment.
