A new method of synthesis of nanosized metal oxide powders (Al2O3, MgO, ZnO) has been suggested. The method involves successive heat treatment at 350°С and then at 800°С of saturated solutions of the corresponding metal salts and sucrose. Physicochemical and technological properties of the synthesized materials have been determined. 相似文献

A new method for producing a nanosized γ-Al2O3 powder was proposed, by which a saturated solution of aluminum oxychloride and sucrose was subjected to sequential heat treatment to 350°C to form a transient species and then to 800°C to form a nanosized γ-Al2O3 powder. The optimal treatment parameters were determined. Stages of the process were identified. The transient species and the nanosized γ-Al2O3 powder were studied. 相似文献

A new method was proposed to increase the crystallization rate in growing single crystals of quartz. In this method, the crystallization is accelerated by using surfactants (polyethyleneamine, tetramethylammonium base, and polyethyleneimine) added to a soda-alkaline solution of standard concentration. Within studied ranges of pressures and concentrations of components of the solution, polyethyleneimine at a concentration of 0.002–0.05 wt % is the most efficient crystallization accelerator, which can increase the quartz crystal growth rate on the average by a factor of 2. 相似文献

A new method of synthesis of nanosized aluminum oxyhydroxide (AlOOH, boehmite) powders has been suggested through a hydrothermal treatment of nanosized γ-Al2O3 powder in water and a 1.5 wt % HCl solution at different temperatures. It has been found that hydrothermal treatment in a 1.5 wt % HCl solution leads to the purification of the starting material; different treatment durations allow one to obtain boehmite particles of different shape. It has been demonstrated that a nanosized boehmite powder is obtained upon the hydrothermal treatment of a nanosized γ-Al2O3 in water above 80°С. The nanosized boehmite powders synthesized at different temperatures have been studied by various methods. 相似文献
