The environment model is used to describe the location of carbonate in nine carbonated apatites containing varied percentages of carbonate and Na+, K+, or NH4+ ions. Unlike the traditional model for carbonate substitution, which identifies different

The identification and characterization of lead-bearing and associated minerals in scales on lead pipes are essential to understanding and predicting the mobilization of lead into drinking water. Despite its long-recognized usefulness in the unambigu

A new model for the location and distribution of carbonate ions in carbonated apatite was used to assign the IR spectra of A- and AB-carbonated apatites. The percentage of total carbonate as measured by the mass loss in the TGA of these compounds is

In this first exploration of europium-doped carbonated apatites the location of carbonate was determined using the environment model for the analysis of IR and NMR spectra. Europium-doped carbonated apatites, containing Eu/(Eu + Ca) mole ratios of ab

The fluorophosphate ion has been widely used as a source of fluoride in dentifrices because of its anticaries properties. Because it is isoelectronic with sulfate, which is known to replace phosphate in apatite, fluorophosphate could be expected to r

The three branched oligogermanes (Me 3 Ge) 3 GePh, (Me 2 Bu t Ge) 3 GePh, and (Me 2 PhGe) 3 GePh were synthesized via the hydrogermolysis reaction and were characterized by NMR ( 1 H, 13 C, and 73 Ge) spectroscopy. In addition, these three compounds

The substitution of sulfate in apatite is of potential importance in synthetic biomaterials used in bone repair and reconstruction. The counter ion (e.g., Na + , K + , Mg 2+ , Sr 2+ ) in the sulfate reagent may also be used as a source of medically b

A modification of the aqueous addition method for the synthesis of apatites is described. This one-step method does not require addition of reagents and no adjustment of solution pH and therefore requires less equipment and less time than the traditi
