Red is love, passion, ideal, and celebration. Its positive symbolic meaning and beautiful color make it one of the most widely used colors in enamel products. Let’s talk about the strongest red pigment today — Cadmium Red .

Cadmium red, commonly known as the big red pigment, is also called cadmium selenium sulfide or cadmium sulfur selenide because it is composed of cadmium sulfide and cadmium selenide. Its color is saturated and vivid, and its color spectrum can range from yellow to red, through red to purple sauce. The higher the CdSe content in cadmium red, the stronger the red light and the darker the color. Its particle shape is basically spherical, and its crystal structure is mainly hexagonal crystals, but also cubic crystals. Its heat resistance is about 600°C, and it decomposes violently above 800°C. Cadmium red has excellent weather resistance and corrosion resistance, strong hiding power, insoluble in water, organic solvents, oils and alkaline solvents, slightly soluble in weak acids, soluble in strong acids, and will release toxic gases H2Se and H2S.

The industrial production of general-purpose cadmium red often uses three kinds of calcining method, precipitation-calcining method and hydrothermal method.

In addition to the enamel industry, cadmium red is also widely used in ceramics, glass, coatings, plastics, art paints, printing inks, paper, leather, colored sand, building materials, and electronic materials.
