Features of synthesis and sintering of environmentally friendly materials involving copper and sodium niobate
The ceramic of solid solutions of binary system (1-x)NaNbO <sub>3</sub> – x/2CuNb <sub>2</sub>O <sub>6</sub> (where x = = (0,100 – 0,325)) were obtained using conventional cersmic technology. The processes of phase formation at the stage of synthesis and sintering facilities were investigated. Shown that sintering of ceramics is the direct effect of Cu-containing liquid phases and and their impact depends on the used qualifications Nb <sub>2</sub>O <sub>5</sub>. The best results were obtained using reagent qualifications " Nbo-pt ".
