Bil2Ti020 material was prepared by solution hydrothermal method. Crystals with graded structure such as micron ball, micron flower, nanorod and nanowire were synthesized. For controllable morphology, this paper analyzes the reaction temperature, reaction time, pH and PVA concentration on Bil2Ti020 morphology and structure, the [...]
Rhenium itself has no independent deposit, and is often dispersed in other non-ferrous ore bodies. It is mainly associated with molybdenite and mostly occurs in trace minerals such as molybdenum, copper, lead, zinc, platinum and niobium. Therefore, we should make full use of regional [...]
Preparation of Ruthenium trichloride directly from ruthenium-containing waste material Ruthenium trichloride is one of the most important compounds of ruthenium and is an important chemical raw material in the fields of heterogeneous catalysis, homogeneous catalysis, electroplating, coating and so on. A method of preparing [...]
Strontium isotope ratio (87Sr/86Sr) is widely used in the fields of earth science, astrochemistry, environmental chemistry, food origin traceability, archaeology and so on. Thermoionization mass spectrometers (TIMS) have been regarded as the benchmark technique for 87Sr/86Sr ratio analysis since the 1960s. This method not [...]
Also a kind of inorganic metal tungsten compound, ammonium paratungstate and ammonium metatungstate have certain differences in performance, production technology and application. First, the former is insoluble in water, the latter is easily soluble in water, and the aqueous solution is quite stable; Second, [...]
Although the current use of holmium and erbium is still limited, some are equal to people’s further development, but it is certain that, with the development of science and technology, the application of holmium and erbium will be more and more widely, more and [...]
