Application of high-level calcium carbonate for synthesis products in the system NA2O–AL2O3–CAO–CO2–H2O

Article preview

The results of synthesis hydrocarboalyuminates of calcium (GKAK) using carbonate reagents of different nature and size distribution. A high activity of the lime sludge from causticising soda and food processing conversion of phosphogypsum, which allows us to recommend them for use in the process of obtaining GKAK. Installed limiting stage of interaction of internal diffusion of the reactants.

About directions of stabilization grain size metallurgical alumina

Article preview

The materials physical and chemical analysis of the reasons of instability particle size distribution of productional of aluminum hydroxide in the processing of bauxite by Bayer process. Shown that the frequency of changes in the properties precipitate Al(OH)3, formed during the precipitation of aluminate solutions determined by the dependence of  the growth  processes on   the relative supersaturation of the system per unit area of the seed. Found determines the influence of concentration injected seed aluminum hydroxide and its active  surface  (which  varies under the influence of impurities in the aluminate solution) on the parameters of the periodic changes in the properties of  sediment.

The effect of degree of metastable solutions оn mass crystallization kinetics

Article preview

The materials of the pilot study, which establishes the dependence of the kinetics of mass crystallization of aluminum hydroxide on the extent of metastable alkaline aluminate solutions. Shown that changes in the level of metastability of the environment of crystallization is the lag in time from changes in state parameters of physico-chemical system. The theoretical a justification of the transition from one level of the metastable state to another due to time constraints, changing the structure of unstable solutions.

Character of constant component of phase voltage of ore-heat furnaces for phosphorus and calcium carbide production

Article preview

On example of phosphoric and carbide furnaces is considered character of change and the nature of existence a constant component (Ucc) in a phase voltage of ore-smelting furnaces with closed furnace throat. The size and direction Ucc depends on a ratio of electrode processes chemical interaction with reactionary zone components and a degree of development and a condition of burning electric arch.
