ABSTRACT:

The study is devoted to development of technology for chemical synthesis of a tungstate and oxidic tungsten bronze of lead in the eutectic ionic fusions of three – (Li, Pb//Cl, WO₄; Na, Pb//Cl, WO₄; K, Pb//Cl, WO₄) and four – component (Li, Na, Pb//Cl, WO₄; Li, K, Pb//Cl, WO₄ and Na, K, Pb//Cl, WO₄) mutual systems. The proposed way of synthesis of a tungstate of lead provides  the process at low temperatures (600–650°C), unlike the existing ways.
