It can be seen from XRD analysis results, (i) mineral dissolution along with formation of alunogen and bassanite in sulfuric acid (ii) formation of merlinoite, dawsonite and brushite
in phosphoric acid, that they can explain an increase in swelling and a decrease in compressibility of soil.
stone is a hard phosphate mineral with an increasing incidence rate, and a quarter of calcium phosphate (CaP) patients form stones containing brushite
In mixed stones (Table 4), the presence of minute quantities of brushite
(<5%) in stones containing carboapatite (#12 and #75) is also not unexpected since brushite
is considered to be a crystalline precursor of the latter, a clinically useless information .
 Factors associated with stone clearance rates after SWL include size of renal calculi, stones within dependent or obstructed portions of the collecting system, stones of certain composition (cystine, calcium oxalate monohydrate and brushite
), and obesity or a body habitus that inhibits imaging and targeting of the stone.

Some reflection are from HA, biologic nonapatitic calcium phosphates include amorphous calcium phosphate such as dicalcium phosphate dehydrate (DCPD), CaHP[O.sub.4].2[H.sub.2]O (Brushite
), another in samples source of 10%, 20%, 50% MgHA from [Mg.sub.3] [(P[O.sub.4]).sub.2].
The most frequent individual crystalline component is calcium oxalate (70-80%), though up to 50% of these can also include calcium phosphate either in the apatite or brushite
