What’s theMosi2 Electric Heater Element?
Molybdenum disilicide(MoSi2) heating element is one resistance heating component made from MoSi2 or as the basic material. When it’s heated to high temperature under the oxidizing atmosphere, one dense MoSi2film will be formed on its surface to protect the element against oxidizing further. Therefore, the element has unique anti-oxidation property under high temperature atmosphere. The highest temperature can reach 1800°C, the applicable temperature is between 500-1700°C.
Mosi2 heating element is a special product combined metal and ceramics. So it has the characteristics of silicon and molybdenum.
Molybdenum disilicide (MoSi2) is a refractory metal silicide that is primarily used as a heating element. In recent years, its potential for use as a structural ceramic has been recognised, as the material combines excellent oxidation resistance and high elastic modulus at elevated temperatures.
Application: It can be used as heating elements of industrial high-temperature furnace, like ceramics, magnetic materials, glasses, metallurgy, refractories etc.
Application of MoSi2 heater:
| Item | name | distinction criterion | specification | Using range |
| Heating elements | 1700 type | Element operating temperature 1700℃ is acceptable | Le Φ 6-12W type/U type/L type/all kinds of hetero type / stripe shape | high temperature electric resistance furnace |
| 1800 type | Element operating temperature 1800℃ is acceptable | |||
| 1800J type | Element operating temperature≥1800℃ | Le Φ 3-12W type | Special,high temperature and high-power electric resistance furnace | |
| 1800T type | Element operating temperature≤1800℃ | Le Φ 3-12W type U type | Not oxidized special air high temperature electric resistance furnace |
Main features:
1.The leading products of the company Molybdenum Disilicide Heating
Element Type 1700grade and 1800grade elements are high-tech
products researched and developed by experts from China and abroad.
2.MoSi2 heating element can quickly form a thin and adhesive
anti-oxidizing layer of quartz glass (SiO2), under the high
temperature oxidizing condition. If the protective layer was
damaged, the element can reform a new one, so MoSi2 heating
elements have a very good anti-oxidation properties, it also means
that the heating element can be used on operation for a much longer
time than the traditional one.
3.The resistivity of the Mosi2 heating element is not changing with
the time, so a new one can be installed without effecting the old
one. This can result of the huge saving in furnace maintenance fee
sand time as well, increase the working efficiency. This is the key
point of Mosi2 heating element being a better material and being
widely used.
2. Physcial property of molybdenum disilicide heating element MoSi2 rod:
| Density | Bending Strength | Hardness | Apparent Porosity | Water Absorption | Elongation | Fracture Toughness | Compressive Strength |
| 5.8g/cm3 | 350Mpa | 12.0Gpa | ±2% | 0 | 4% | 4.5Mpa.m1/2 | 650Mpa |
