CdO (Cadmium Oxide)

Notas

In ceramic glaze formulations, cadmium oxide serves as a critical component for color development rather than acting as a primary glass former or flux. It is chemically inert regarding pigmentation on its own; however, it functions as a essential precursor for vibrant hues when combined with other elements. Specifically, the integration of cadmium oxide with selenium is utilized to achieve red colorants, while its reaction with sulfur results in yellow shades. Achieving these colors, particularly the yellow tones, requires precise control of kiln conditions, as a slightly reducing atmosphere is necessary to prevent the loss or degradation of the colorant system.
