Title: | Postopek priprave keramike na osnovi alkalijskih niobatov in alkalijskih niobatov tantalatov z mehanokemijsko aktivacijo [SL], Procedure of Preparation of Ceramics Based on Alkali Niobates and Alkali Niobate Tantalates by Mechanochemical Activation [EN] |
Description: | The subject of the invention is a procedure of preparation of ceramics based on alkali niobates and alkali niobate tantaletes by mechanochemical activation of the starting mixture of powders. Starting powders are first homogenised in acetone or a similar organic solvent, then mechanochemically activated by dry grinding, heated, ground again in an organic solvent, dried, pressed in shapes and sintered at higher temperatures. After the heating of the mechanochemically activated powder, the formed alkali niobate or alkali niobate tantalate does not contain any secondary phases. |
