This is because of their thermal stability, absence of chemical affinity with ferrous materials and mainly because of the lower wear they suffer [6].
A common use of these wheels is for manufacturing low machinability materials, in which usually vitrified bonded CBN wheels are used.

Electrical degradation is a major concern in the development of new varistor materials.
Experimental Raw materials were prepared to obtain ceramic compounds with nominal composition of 98.2 mol % ZnO + 0.8 mol % Pr6O11 + 0.6 mol % Cr2O3.
The value held well below the 10% limit of allowable variation in Eb for commercial varistor materials.
