1. The influence of the introduction of 0.05 to 3.0% K2O into a catalyst of 15 mol. % Cr2O3-Al2O3 on the activity and selectivity of the action in the decomposition of i-C3H7OH, on the value of the specific surface S, on the electroconductivity at 300° σ300, the activation ...
2.2. Preparation of CaO-K2O catalyst from waste golden apple snail shell and cultivated banana peel The mixture of dried golden apple snail shell and cultivated banana peel, which had a mass ratio of 3:1, was further crushed and sieved until it was fine enough to pass through screens of 70...
In general, the use of a self-flux, i.e., a solvent for which all the ions are the same as those of the solute to be grown, is preferred. This is widely encountered for KNN-based single crystals grown from high-temperature solution (example of solvent: K2O) [54,55]. On the other...
