He aha ka pigment ʻulaʻula cadmium a pehea e pili ai ka selenium i kona ʻano?
ʻO ka pigment ʻulaʻula Cadmium he cadmium sulfoselenide, nona ka cadmiumsulfidea me 10–25% cadmium selenide. Noho nā ion Selenium i nā wahi lattice, e hana ana i nā ʻano hue mai ka ʻalani a i ka ʻulaʻula hohonu ma ka hoʻololi ʻana i ka lakio CdS:CdSe. Hōʻoia ka matrix crystalline i ka ikaika kiʻekiʻe a me ke kūpaʻa. Hoʻonui ka Selenium i ka vibrancy kala a hoʻolōʻihi i ka lōʻihi o ka pigment, koʻikoʻi no nā kala pena kiʻi mau loa, māmā a me nā mea ʻoihana.
Pehea e kōkua ai ka spectroscopy XRF i ka ʻike ʻana i ka pigment?
ʻIke pololei ka spectroscopy XRF i ka cadmium a me ka selenium i loko o nā matrices pigment paʻa no ka loiloi kemika pigment non-destructive. ʻO nā piko elemental, me ka cadmium Kα (23.2 keV) a me ka selenium Kα (11.2 keV), e ʻae i ka ʻike wikiwiki ʻana i ka haku mele pigment. Hoʻokaʻawale pololei ke ʻano hana i nā pigments selenium mai nā ʻano ʻē aʻe, me nā palena ʻike ma lalo o 50 ppm ma muli o ke ʻano matrix a me ke ʻano o ka laʻana.
No ke aha he mea nui ka ʻike ʻana i ka nui o ka selenium i loko o nā pigments?
Pono ka palapala ʻana i ka nui o ka selenium no ka palekana o ka pigment, ke kūlike o ka hana ʻana, a me ka mālama ʻana i nā lula honua e pili ana i ke kaiapuni a me ka ʻike ʻana o ka limahana.
