1.MoSi2 hetaer Molybdenum disilicide heating element, 2.type:U,W,UL,WL,Rod ., 3 Dia(mm):3/6,4/9,6/12,9/18,12/24 - details see: https://www.machineto.com/iso-quality-molybdenum-disilicide-heating-element-mosi2-furnace-heater-10247562

STA MoSi2 Heater Molybdenum Disilicide Heating Elements 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 Heater Molybdenum Disilicide 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.It is used to the highest temperature up to 1800C during oxidizing atmosphere. According to your request, our company can produce the products of Rod,"U", "W" and "U"-right angle ,"W'---right shapes, etc.

MoSi2 Heater Molybdenum Disilicide Heating Elements is used in the high temperature under oxidizing atmosphere. It will form the SiO2 film which can keep the element from being melted. When the temperature of element is more than 1700°C,the MoSi2 Heater Molybdenum Disilicide Heating Elements must not be used in the temperature between 400°C and 700°C for a long time; otherwise the element will be cremated under the strong oxidizing function in the low temperature.

DryH2	1350°C	1450°C	1600°C

The brittleness of MoSi2 Heater Molybdenum Disilicide Heating Elements is relative more under the usual temperature, it also has plasticity under the high temperature. So you had better hang and erect vertically the "U"-shape element. If you need to erect it horizontally, please choose a support of high-temperature insulating materials. The cone-part of the element must extend inside the furnace. At first the fixture of MoSi2 power connector cant be screwed too tightly. When temperature of the element is going up, please twist it tightly again, so the element is not easily broken.

Our suggestion: please choose the specialize power connector provided by our company) The furnace top must be a good function of heat-preservation. In general, the temperature of furnace top cant be over 300C. The voltage should be low 0.1 between the power connector and the element. In order to avoid radiating heat to pass the connector, the distance is not less than 50mm between the low end of connector and the upside of the ceramic brick. The Dia.6 element cant be used of 170A for a long time. The Dia.9 element cant be used of 300A for a long time.
