Extraction of alumina from clays and high-silica bauxites.
Two processes for extracting alumina from low-grade ores are described, one applicable to both clays and high-silica bauxites, and the other only to bauxites. In the former process, a line-containing sinter is prepared and annealed by cooling it slowly through the range of 1,3000 to 1,2000 C. The annealed sinter dusts to a powder which requires no grinding. This material is extracted with a sol...
متن کاملWater reduction by photoexcited silica and alumina.
Excess electrons in solvent are amongst the most fascinating chemical species, at the very edge between physics and chemistry. In this contribution, we report the use of silica and alumina photochemistry to create and stabilize aqueous solutions of electron.
متن کاملKinetics of Ceramic Phase Crystallization in a Glass Derived from Wastes of Iron and Steel Industry
Intensified environmental regulations have posed numerous challenges in the disposal of industrial wastes. The steel industry is one of the biggest production industries, with a considerable amount of daily wastes. Production of glass-ceramic from the steel industry waters is one of the proper solutions for this problem. In this study, the application utilization of different wastes (such as bl...
متن کاملRelating Grain Boundary Complexion to Grain Boundary Kinetics II: Silica-Doped Alumina
This second paper in a series describes the relationship between grain growth kinetics and grain boundary complexions in silicadoped alumina. Dense high-purity silica-doped alumina samples were annealed for various times in the temperature range of 13001 and 19001C and their grain growth behavior was quantified. Four different grain boundary complexions were observed in silica-doped alumina, al...
متن کاملPyrolysis Characteristics and Kinetics of Food Wastes
Pyrolysis is an environmental friendly alternative method compared with incineration, and the least time-consuming and smallest infrastructure footprint method compared with bio-chemical and thermo-chemical conversion. Baseline data for the pyrolysis of food waste was obtained in a kinetic study of the thermal decompositions by thermogravimetric analysis. To simulate the difference in the types...
