composed of aggregates of crystals; "polycrystalline metals"
Composed of more than one crystal or grain.
Composed of aggregates of crystals. Of many crystals.
A material which is made to have many small crystal grain boundaries instead of one large monocrystalline structure. Materials are made polycrystalline to increase their flexibility and strength.
a material made up of grains of crystalline material where the grains are randomly oriented relative to each other. The material has short range but no long range order.
Refers to a mineral made of many small crystals.
A semiconductor (photovoltaic) material composed of variously oriented, small, individual crystals.
