Isotopically pure diamond 98.9% C and 1.1% C. This is useful for heat sinks for the semiconductor industry. Isotopically pure C diamond layers 20 micrometers thick are used as stress sensors due to the advantageous Raman spectroscopy properties of C. Isotopically pure diamond An isotopical pure diamond is a type of diamond that is composed entirely of one isotope of carbon.
