High temperature antioxidant property:
At a high temperature oxidizing atmosphere, 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 1700C, 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.
Note: the element can’t be used for a long time in the temperature range of 400C to 700C, otherwise it will be strongly oxidated and damaged
