Pigmentc, are widely used in commercial compositions of plastics, rubbers, ceramics, printing inks, cosmetics and paints. The paints as surface coating compositions can be decorative or protective. In the field of aircraft, the outside finish must also protect against fluctuation of temperature, Intense ultraviolet radiation and Impact with raindrops at high velocity.
In this work a series of yellow to buff and blue to green pigments were prepared by the calcination process at 1100 C. Their spectral characteristics were measured and the relation between the absolute spectral data and wavelength of the incident radiation in the range of 400-1100 nm were given. The effect of percentage of pigment composition and the time of calcination were shown. The spectral data were measured for the pigments In powder and film forms. A discussion on the use of such inorganic pigments in the field of aircraft was reported.
