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

摘要

The α-ray emission amount of the black titanium oxynitride pigment is 0.1 cph/cm 2 or less. Moreover, it is preferable that a uranium content is 1 mass ppb or less, and, as for a black titanium oxynitride pigment, it is 5 mass ppb or less of thorium content.
