Abstract
Light turquoise pigment was synthesized by solution combustion of a mixture containing Al(OH)3, solutions of boric, citric, and phosphoric acids, and copper nitrate and subsequent annealing at temperatures up to 900°C. To increase the thermal stability of pigments, the synthesis was carried out using an aluminophosphate binder. The synthesized pigments were found to contain amorphous borates, boron phosphate, phosphates and pyrophosphates of aluminum and copper. The copper phosphide CuP2 impurity formed during the synthesis process and subsequent annealing at 700°C gives the pigment a grayish tint but increases its anticorrosion properties.
期刊介绍：
International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
