Mosi2 heating element are classified based on their temperature range, including the 1700 Grade, 1800 Grade, 1850 Grade, and 1900 Grade.
During usage, it is important to control the temperature of the mosi2 heating element based on the electrical parameters at different temperature ranges. It is crucial not to exceed the maximum limits of the element in order to achieve the desired furnace temperature. It is not desirable to thicken the diameter of the elements for raising the furnace temperature.
The following graph provides a reference for the resistivity and temperature curves of heating elements of types 1700, 1800, and 1900.

In cases where the power is matched to the heating rate, it is necessary to select a mosi2 heating element suitable for the desired temperature.If the actual temperature exceeds the operating temperature of the MoSi2 heating element, it will lead to damage of the MoSi2 heating element.
