In the ancient reactor, the aluminum phosphate
captured almost all the noble gases, effectively reducing environmental contamination, Meshik notes.
To determine why aluminum phosphate shows such a remarkable recovery when other crystalline materials do not, John S.
In contrast, both experiments and simulations show that a crystalline form of silicon dioxide known as alpha-quartz, which has the same tetrahedral atomic arrangement as aluminum phosphate, fails to recover from its pressure-induced, disordered state.
Jeanloz conjectures that the memory effect of aluminum phosphate
, and of several other crystals tested, depends on the experiment's room-temperature conditions, which probably prevent the squeezed ions from wandering more than a smidgen from their original sites.
Rhone-Poulenc recently announced two other investments in Nashville, one in 1995 to expand sodium aluminum phosphate
production, and one $4 million investment in January, 1996 to expand production of sodium hypophosphite.
Along with these, microbes also use solubilizer phosphates such as tricalcium and aluminum phosphates
, and make them available to plants.
For example, at a low pH, phosphorus is precipitated as iron and aluminum phosphates
which are relatively insoluble and unavailable.
