Resistivity of MoSi2 (Molybdenum Disilicide) heating element rises dramatically when temperature rises. Power output is less than 35% of the max. output at 300°C. Resistance of a MoSi2 heating element does not change under normal use, and you can mix new and old elements together.
Generally a separator should be placed in between two shanks of heating element when installing the heating elements in the furnace. Please make sure the width of the separator matches the space of the heating element. If the separator is too big it may break the heating element during installation.
