PROPERTIES OF THE MMO COATING
The MMO (Mixed Metal Oxydes) coating is a homogenous blend of Mixed Metal Oxides.
This coating has the following properties :
A cristalline structure which enables MMO coatings to be ceramics which are highly resistant to mechanical forces.
A high metallic conductivity which justifies their use as an electrode coating.
A high specific surface which allows increased and homogenous current densities to be obtained.
The mixed metallic oxides also show excellent resistance to acid electrolytes.
Reduced sensitivity to the residual ripples from the rectifier.
Unlike the platinum coating, the MMO coating is little affected by power supply ripples. A 5% ripple causes a variation of only 5mV in the interface potential.
