BLACK TITANIUM OXYNITRIDE PIGMENT METHOD FOR PRODUCING SAME AND SEMICONDUCTOR-SEALING RESIN COMPOUND USING BLACK TITANIUM OXYNITRIDE PIGMENT

摘要

The -ray emission amount of the black titanium oxynitride pigment is 0.1 cph / cm 2 or less. It is preferable that the black titanium oxynitride pigment has a uranium content of 1 mass ppb or less and a thorium content of 5 mass ppb or less.
