potassiumsodiumX-ray diffractionThe interaction of TiN with Na2O–K2O–P2O5melts was investigated at (Na+K)/P molar ratios of 0.9, 1.0, and 1.2 and at Na/K molar ratios of 1.0 and 2.0. Interactions in the system led to the loss of nitrogen and the partial loss of phosphorus and ...
(136) were recovered. These results are attributed to the low nucleophilicity of indole. To confirm the importance of a base, we added potassiumtert-butoxide. Indeed, the reaction smoothly proceeded to provide product15in 72 % yield in the presence of DMAPO (1 mol %) and potassium...

The new mineral zincoberaunite, ideally ZnFe(PO)(OH)·6HO, the Zn analogue of beraunite, is found in the Hagendorf South granitic pegmatite, Hagendorf, Bavaria, Germany, in two associations: (1) with potassium feldspar, quartz, jungite, phosphophyllite and mitridatite (the holotype) and ...
A total of 4 g of graphite powder was added into a solution composed of 2 g of potassium persulfate (K2S2O8) (J. T. Baker, Phillipsburg, NJ, USA), 2 g of phosphorus pentoxide (P2O5) (J. T. Baker, Phillipsburg, NJ, USA), and 30 mL of conc. sulfuric acid (H2SO4). The ...
The MKPC physicochemical stability improved with the increase in the M/P ratio, higher mechanical strength, and more refined pore structure. Keywords: magnesium potassium phosphate cement (MKPC); immobilization of Al radioactive waste; corrosion; hydrogen release; pH; pore ion content...
