Cordierite Wirewound Core for Power Resistor.

Cordierite Ceramic (2MgO-2Al2O3-5SiO2)

Cordierite ceramic is a type of magnesium aluminum silicate with particularly good thermal shock properties due to its porous structure. Cordierite also has low thermal conductivity and thermal expansion. This is mainly a structural ceramic, often used for kiln furniture due to its extremely good thermal shock resistance. Also used in other applications where rapid temperature changes take place. It’s also a cost-effective material when compared with other ceramic materials, therefore it’s an ideal material to use in heating applications.

The advantages of cordierite ceramic:
– Electrical insulation
– Mechanical strength
– Low density
– Resistance to high temperatures
– Resistance to thermal shock
– Resistance to climate and ageing
– Environmentally compatible disposal
