The material used in a muffle furnace depends on the temperature requirements of the furnace. For a muffle furnace with a temperature of 1100°C, the heating chamber is made of ceramic fiber board. Ceramic fiber board is a type of insulation material that can withstand high temperatures and provides insulation to keep the outer surface of the furnace at a minimum temperature.
For a muffle furnace with a temperature of 1400°C, Ceramic Zirconium board is used for the heating chamber. Ceramic Zirconium board is a high-temperature resistant material that can withstand even higher temperatures than ceramic fiber board.
In addition to the heating chamber material, the muffle itself is typically made of a ceramic material such as alumina. Alumina is chosen for its ability to withstand high temperatures and resist chemical corrosion. The muffle provides a separate chamber for the material to be heated, isolating it from the surroundings and protecting it from direct exposure to the heating elements.
Overall, the materials used in a muffle furnace are selected based on their ability to withstand high temperatures, provide insulation, and resist corrosion, ensuring efficient and controlled heating of materials.
