DISTRIBUTION FUNCTION OF PRECIPITATED TIO2 PARTICLE VOLUMES
Show abstract
The distribution function of precipitated particles in relation to their volume is modelled by a function reproducing the three moments of the real function. The time evolution of the distribution is simulated by the numerical solving of a non-linear differential equation system for the moments, resulting from the rate equation which describes the growth of the particles.

UTILIZATION OF NMR-SPECTROSCOPY FOR THE DETERMINATION OF POLYACRYLAMIDE SOLUTIONS CONCENTRATION
Show abstract
A method of the determination of the concentration of the Medasol type hydrolized and non-hydrolized polyacrylamide in aqueous solution by higy resolution MNR is presented. The method may be applied to dilute solutions under the conditions presented in this paper.

INFLUENCE OF PHOSPHORIC-ACID AND OF PERCHLORIC-ACID ON ELECTROFORMATION OF ELECTRODES OF LEAD-SULFURIC ACID BATTERIES
Show abstract
The microstructure modifications have been studied during the electroformation of positive and negative plates which give information regarding the optimal conditions for the obtaining of plates for lead batteries. The microstructure proved to depend on the conditions under which the electroformation takes place and on the nature of the electrolyte additions. The SEM studies showed that in the positive active mass, the particles are heterogeneously scattered and that they consist of amorphous and crystalline areas.
