Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If porcelain labware equivalents
Similar ceramics used for laboratory crucibles rather than electrical insulation use porcelain labware classification.
If refractory cordierite bricks
Cordierite products for furnace linings are refractory materials, not electrical insulators.
