The compound formed between AlCl 3 and NH 3 at room temperature and low temperature, characterized by different analysis methods, corresponds to the formula AlCl 3 路 6NH 3 . This intermediate was heated to 900 掳C under an ammonia stream to obtain aluminium nitride in low yield; as by-...
alum,ammonia alum,ammonium alum- a white crystalline double sulfate of aluminum: the ammonium double sulfate of aluminum bauxite- a clay-like mineral; the chief ore of aluminum; composed of aluminum oxides and aluminum hydroxides; used as an abrasive and catalyst ...
Aluminium hydroxide may be prepared as a gelatinous precipitate by adding ammonia to an aqueous solution of an aluminium salt. It is amphoteric, being both a very weak acid, and forming aluminates with alkalis. It exists in various crystalline forms. ...
Or aluminum chloride and ammonia by gas phase reaction. The coating can be synthesized by vapor deposition method from AlCl3-NH3 system. AlN 3H2O = = catalyst = = = Al(OH)3 ↓ NH3 Use Is a good heat shock resistance material, is an ideal crucible material for casting pure iron, ...
1) high-purity Aluminium and Zinc 高纯铝、锌2) High purity zinc 高纯锌 1. A new process of using ammonia and ammonium chloride solution to leach zinc oxide fume dusts and electrowinning high purity zinc was explored successfully. 开发了用NH3 NH4 Cl水溶液浸出炼铅炉渣烟化炉氧化锌烟灰制取...
control of the chemical composition and simple set-up. Previously, our group have demonstrated sol–gel deposition of p-type ZnO via co-doping method [20,21], using the combination of aluminium chloride and ammonia hydroxide. One of the key findings of the ...
