ACP is a unique calcium phosphate in that it lacks long-range crystalline order. Yet the constancy in the composition of ACP over a wide range of solution conditions suggests a well-defined local structural unit. Although this order within disorder is the most distinguishing feature of ACP, the solution instability of ACP and its ready transformation ...

Canine Calcium Phosphate Uroliths
Veterinary Clinics of North America: Small Animal Practice, 1986Uroliths composed primarily of calcium phosphate are identified in approximately 3 per cent of canine stone patients. Predisposing factors to the formation of calcium phosphate uroliths include elevated urine pH, hypercalciuria, and the presence of crystallization inhibitors and promoters.

Calcium Phosphate in Catheter Encrustation
British Journal of Urology, 1987Summary— Encrusted catheters from nine female patients were the source of samples of deposits which were examined by X‐ray diffraction, atomic absorption spectroscopy, infra‐red spectroscopy and extended X‐ray absorption fine structure (EXAFS) spectroscopy. In eight samples the only crystalline phase which could

Determination of calcium in official calcium phosphates
Journal of Pharmaceutical Sciences, 1967The assay of official calcium phosphates for calcium can be brought into the general method for calcium determination by titration with EDTA using hydroxynaphthol blue indicator by dissolving the sample in a strictly limited amount of hydrochloric acid, passing an aliquot of the solution through a column of anion-exchange resin in the chloride form ...

XRD Analysis of Calcium Phosphate and Biocomposite Calcium Phosphate/Bioresorbable Polymer
Materials Science Forum, 2006Composite biomaterials based on calcium phosphate ceramic due to their high bioactivity are of interest for biological application and bone tissue repair. Structural and microstructural parameters of inorganic constituent of these materials are very important for the synthesis and characterization of composites.

Tympanoplasty With Calcium Phosphate
Archives of Otolaryngology - Head and Neck Surgery, 1984In 35 patients, with an average follow-up period of 2 1/2 years, the middle ear was reconstructed with prostheses of hydroxyapatite, which is the main substance of living bone tissue. In case of a missing incus, an interposition prosthesis of dense hydroxyapatite was used.

Amorphous calcium (ortho)phosphates
Acta Biomaterialia, 2010Amorphous calcium phosphates (ACPs) represent a unique class of biomedically relevant calcium orthophosphate salts, having variable chemical but essentially identical glass-like physical properties, in which there is neither translational nor orientational long-range ordering of the atomic positions.

Calcium and phosphate usually form part of a ‘bone’ profile of tests that also includes measurement of serum albumin and alkaline phosphatase levels. Most laboratories report total calcium concentration in serum. This is influenced in particular by serum albumin concentration, and the total calcium is therefore also adjusted for the serum albumin ...
