A lab furnace can reach different maximum temperatures depending on its type and purpose.
For standard lab furnaces, the maximum temperature typically ranges between 975°C and 1,700°C. These furnaces are equipped with a PLC controller to regulate temperatures from 100°C up to the maximum temperature. However, standard lab ovens do not maintain temperatures above 350°C.
There are also high-temperature furnaces available in the laboratory setting. These furnaces can reach higher temperatures, ranging from 1400°C up to 1800°C. They are designed with heating elements located on both sides of the heating chamber to ensure good thermal uniformity. High-temperature furnaces are commonly used for processes such as sintering of high-temperature materials, glass melting, high-temperature testing of ceramics, fusion and firing processes, and powder metallurgy processes.
In the specific case of dental furnaces used in dental laboratories, the most advanced ones on the market can reach temperatures up to 1600°C. These furnaces need to maintain a constant temperature balance throughout the entire cycle duration to avoid inconsistencies in dental work, such as cracks, weak bonds, and brittle material.
It is important to consider the temperature range of a laboratory furnace as it directly affects the processes and outcomes of the products. Different temperature ranges are available for heat furnaces:
1. Heating up to 1300°C: This range uses wire heating element technology and can heat up to 1300°C.
2. Heating up to 1500°C: Silicon Carbide elements can be heated up to 1500°C.
3. Heating up to 1800°C: This range utilizes a molybdenum disilicide (MoSi2) heating element to reach temperatures of up to 1800°C.
Overall, the maximum temperature a lab furnace can reach depends on its design, purpose, and the specific heating elements used.
