摘要
对宝红BK钙盐的α-、β-、γ-、δ-晶相的形成进行了研究,指出色淀化温度和干燥温度是影响晶相生成的重要因素;对α-和β-晶相在不同性质溶剂中的转相速度做了比较实验,结果表明:决定因素是它在溶剂中的溶解度,还提出了金属离子性质对颜料晶相及热性质起了重要作用。
The formation of α-、β-、γ-、δ-crystal phase of Rubin BK pigment was studied, and it was found that the temperatures of laking and drying are important factors. A comparative experiment of the rate of crystal phase transformations in different solvents was carried out. It was found that the solubility is important to the rate of phase transformations and the character of the ionic bond plays an important role in the thermal properties of pigment.
