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.

铜基颜料的合成

摘要通过溶液燃烧含有 Al(OH)3、硼酸、柠檬酸和磷酸溶液以及硝酸铜的混合物，然后在高达 900°C 的温度下退火，合成了浅绿松石颜料。为了提高颜料的热稳定性，合成过程中使用了磷酸铝粘合剂。合成的颜料中含有无定形的硼酸盐、磷酸硼、磷酸盐以及铝和铜的焦磷酸盐。在合成过程中形成的磷化铜 CuP2 杂质和随后的 700°C 退火使颜料呈现灰色，但却提高了其防腐性能。

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.
