polygranular graphite

https://doi.org/10.1351/goldbook.P04731
A @G02687@ composed of grains which can be clearly distinguished by means of optical microscopy.
Note:
From the viewpoint of @C01433@, a polygranular @G02684@ is always a @P04723@ but not vice versa. Most industrial @G02684@ materials are polygranular. Monogranular materials consist mostly of @N04193@, such materials are called monolithic or @A00188@.
