Pigments production for use in different kinds of industries (paints, cement, fertilizer, glass, etc.) is a booming sector that invoice million worldwide. So, all those applications that increase efficiency and effectiveness ...

This study evaluated how the background (white or gray) affects the color parameter measurements and color difference calculations (∆Eab and ∆E00) of dental ceramics. Disc-shaped feldspathic ceramic specimens were prepared ...

Nos últimos anos, o estudo de materiais cerâmicos vem evoluindo muito rapidamente, principalmente os estudos relacionados com cerâmicas avançadas. As diversas aplicações envolvendo esses materiais, tais como pigmentos ...

In the present work, the basic concepts of radiometric, photometric and colorimetric calibration are presented, which were applied to three light-emitting diodes (LEDs) used to compose the different color sensations that ...
