Abstract

There have been determined the composition of liquid complex fertilizers based on low concentrated wet-processing phosphoric acid from washed and calcinated phosphoconcentrated of Kyzylkum. The density and viscosity of the liquid fertilizers were studied at wide temperatures (30-80оС). It was given the list of chemical compounds generated at ammonization of wet-processing phosphoric acid with various impurities. In order to reduce precipitation of residues during the neutralization 26% aqua suspension of bentonite was used as suspendered agent in amount of 1 to 3%. Rheological properties of the nitrogen-phosphate solution show that they are in liquid condition.
