MoSi2 Heating Elements 1700°C 1800°C 1850°C 1900°C

Features

The Mosi2 heater has the function of antioxidant and auto repair, and suitable for different kinds of continuous working during the oxygen atmosphere. Molding by heat process and model size is standard, so we can produce special shapes and sizes according to customer requirements. Adopt a special process for joint molding with fasten welding and strong impact resistance. High density and excellent electrical conductivity, high heating rate, and low power consumption. The old one and the new one could be used together.

High Temperature Antioxidant Property

At a high temperature oxidizingatmosphere, a dense quartz SiO2 protect layer will be generated in the surface of the hot zone to prevent the element from further oxidation. When the temperature is higher than 1700°C , the protection layer would be melt. Due to the effect of surface tension, quartz agglomerating into drops, and loses the protection. Then continue to use in the oxidizing atmosphere, the quartz protection layer again generate.

 

FAQ

MoSi2 Heating Elements Require Special Care
If your furnace uses Molybdenum Silicide, it forms ceramic quartz on the outer surface of the restoration that interacts with green state colorants. Over time, the melting point of this quartz becomes lower than the top temperature of the sintering cycle and this creates pollution in the furnace chamber. As a result, these pollutants can cause greening or darkening of the restorations. In order to prevent this you should always use a covered crucible. This will reduce the likelihood of chamber pollution getting into the restoration.
