Optimal Parameters for Obtaining Diammonium Phosphate from off-balance Phosphate Raw Materials of the Karatau Basin

Diammonium citrate and diammonium phosphate as sources of dietary nitrogen for growing-finishing swine.

Efficient and Eco-Friendly Procedure for the Synthesis of 2-Amino-4H-Chromenes Catalyzed by Diammonium Hydrogen Phosphate

An efficient and eco-friendly protocol for the preparation of 2-amino-4H-chromenes employing a multi-component, one-pot condensation reaction between aromatic aldehydes, malononitrile and1-naphthol has been developed. The reaction of 1-naphthol with malononitrile and various aromatic aldehydes was carried out i...

Transmission Electron Microscopic Study of Tetracalcium Phosphate Surface-Treated in Diammonium Hydrogen Phosphate Solution

The present study investigates the changes in microstructure and microchemistry (particularly Ca/P ratio) during whisker formation on the surface of a monolithic TTCP powder in a basic phosphoric acid solution. The XRD results indicate that when TTCP powder was treated for 10min or less in (NH4)2HPO4 solution, the monolithic TTCP phase remains unchanged. When treated for 30min, apatite whiskers...

Determination of the Nucleation and Crystallization Parameters for Making Nanoporous Titanium Phosphate Glass-ceramics

Nanoporous glass-ceramics were prepared with composition 45CaO-25TiO2-35P2O5 (mol%). Two molar percent of Na2O was added as a flux to the composition. With the aforementioned composition, glass melted and crystallized into glass-ceramics containing β-Ca3(PO4)2 and CaTi4(PO4)6 as the main phases. The differential thermal analysis (DTA) was conducted to determine the suitable temperatures f...
