Mosi2 Heating Element
Product Information
Mosi2 heating element is a kind of resistance heating element basically made of high pure Molybdenum Disilicide. In oxidizing atmosphere, a layer of compact quartz protective film is formed on the surface of Mosi2 elementowing to the high temperature combustion, which prevent Mosi2 from continuously oxidizing. In oxidizing atmosphere, its Max temperafure can reach 1800'C, and its applicable temperature is 500- 1700'C. lt can be widely used in such applications as sintering and heat treatment of ceramics, magnet, glass, metallurgy, refractory, etc.
Features:
1. Good high temperature performance
2. Strong oxidation resistance
3. High mechanical strength
4. Good electrical properties
5. Strong corrosion resistance

The Difference Between 1800 and 1700
(1) The welding joint of 1800 silicon molybdenum rod is full, protruding and bulging, and there is no crack at the welding place, which is different from 1700 type.
(2) The surface of 1800 silicon molybdenum rod is smoother and has metallic luster.
(3) The specific gravity is higher. Compared with 1700 type, 1800 silicon molybdenum rod of the same specification will be heavier.
(4) The color is different. In order to look good, the surface of 1700 silicon molybdenum rod is treated and looks black.
(5) The operating current and voltage of 1800 silicon molybdenum rod are smaller than those of 1700 type. For the same hot end 9 element, the operating current of 1800 type is 220A, and that of 1700 degree element is about 270A.
(6) The operating temperature is high, which is more than 100 degrees higher than that of 1700 degree.
(7) General Applications:
1700 Type: mainly used in industrial heat treatment furnaces, sintering furnaces, casting furnaces, glass melting furnaces, smelting furnaces, etc.
1800 Type: Mainly used in experimental furnaces, testing equipment and high-temperature sintering furnaces, etc.
