However, the precipitation process shows a marked discrimination against strontium and chemically homogeneous solid solutions are obtained only if the ratio of strontium to calcium in the aqueous solution is maintained constant during the precipitation process. The discrimination against strontium decreases ...
The ammoniacal calcium nitrate solution obtained may be evaporated to recover ammonia for re-use and solid calcium nitrate, or be neutralised with nitric acid to obtain a mixture of calcium and ammonium nitrates which may be used as a fertiliser. Liquid, gaseous, or aqueous ammonia may be ...
Encyclopedia / Nitrate / Others / Other Chemicals Calcium nitriteCAS:13780-06-8 MW:132.09 MF:CaN2O4Calcium nitrite, with the chemical formula Ca(NO2)2 and CAS registry number 13780-06-8, is a compound known for its applications in various industries. This white crystalline solid is composed...
In its aqueous form, it is known as limewater, which is a clear solution. Calcium hydroxide is typically stable under normal conditions, but its properties can change when exposed to moisture or air, as it tends to absorb carbon dioxide and convert into calcium carbonate. This compound is ...
Drug and polymer molecules can intercalate and exfoliate the clay particles to form a stable aqueous suspension and improve the aqueous solubility of the drug. The choice of polymer for effective clay dispersion is a very important issue. Clay–drug interaction mechanisms, including hydrophobic ...
Cyanamide is sold as anhydrous, aqueous 50%, and calcium cyanamide. Anhydrous and aqueous 50% cyanamide contain a buffering additive, usually 2% sodium biphosphate to stabilize the pH and prevent formation of dicyanamide and urea.Emulsifiable concentrateCyanamide in 50% aqueous solution: cyanamide=50...
solid solutions of hydroxylapatites Ca10-(m+n)CumZnn(PO4)6(OH)2 with a fixed value of m = 1 are synthesized over the entire composition range using a new coprecipitation technique starting from aqueous NH 4 H 2 PO 4 solution and solutions containing Ca-, Cu-, or Zn-nitrate.doi...
MATERIALS AND METHODS Synthesis of calcium phosphate nanoparticles Calcium phosphate nanoparticles were precipitated from aqueous solu- tions of calcium nitrate (6.25 mM) and diammonium hydrogen phosphate Gene Therapy (2017) 282 – 289 Live-cell imaging and the transfection and gene-silencing efficiency ...

No halo or background irregularity, suggestive of an amorphous phase, were detected. The data obtained reveal that despite a constant liquid to solid ratio of the precursors, the time of the OCP synthesis has increased with the amount of the initial α-TCP used. Hence, the end of the ...
