Witryna15 cze 2024 · All precipitation gravimetric analyses share two important attributes. First, the precipitate must be of low solubility, of high purity, and of known composition if its mass is to reflect accurately the analyte’s mass. Second, it must be easy to separate the precipitate from the reaction mixture. Solubility Considerations WitrynaBased on the saturation mechanism, the growth rate with and without plasma treatment was saturated at 0.24 and 0.46 nm/cycle, respectively. Plasma-treated TiN films had nanocrystalline structures, and the root-mean-square thickness was 0.211 nm. Carbon impurities decreased from 12% without plasma treatment to 3% with plasma treatment.
