Product details

Dia 3/6 4/9 1800 1700 mosi2 heating elements heating element for zirconia sintering furnace

Molybdenum disilicide(MoSi2) heating element:
Mosi heating element is a kind of resistance heating element basically made of pure molybdenum Disilicide. In oxidizing
atmosphere, a layer of compact quartz protective film is formed on the surface of Mosi 2 element owing to the high temperature combustion, which prevents Mosi 2 from continuously oxidizing.

In oxidizing atmosphere, its Max temperature can reach 1800 c and its applicable temperature is 500-1700. It can be widely used in such applications as sintering and heat treatment of ceramics, magnet, glass, metallurgy, refractory etc. the commercial name of our Mosi 2 heating element is KERONE Mosi 2 Heating Element.

Installation of mosi2 heating element

1)Vertically hanging
Under normal temperature, MoSi2 element is very brittleness, while under high temperature, it is plasticity, so the better way to install U Shape element is to hang it vertically from the furnace top through the support clamping chuck. The aim of such way is to avoid putting the mechanical stress directly to the element heat-generating end; otherwise the element will easily be broken.

2) Support clamp
Support clamp are applied to 9/18 and 6/12 two kinds of elements respectively. The support clamp supports the whole weight of the element and the position of the element is also determined by it, therefore, it must be installed carefully to assure the element vertically hung. In order to prevent the element from being over heated locally, the taper part of the element lower end must put into the furnace chamber.
