Impurity's ia
Diamond type is a method of scientifically classifying diamonds by the level and type of their chemical impurities. Diamonds are separated into five types: Type Ia, Type Ib, Type 1aB, Type IIa, and Type IIb. The impurities measured are at the atomic level within the crystal lattice of carbon atoms and so, unlike inclusions, require an infrared spectrometer to detect. Different diamond types react in different ways to diamond enhancement techniques. Different ty… Witrynaimpurities are compared, there is limited indication of interaction between impurities. For example, copper improves the efficiency of Ti- and V-doped cells, although the …
