Effects of pH on heavy metal sorption on mineral apatite
Nanobacteria in the mitral valve can cause calcium phosphate calcifications (local calciphylaxis) in the form of carbonate apatite
in a patient on continuous ambulatory peritoneal dialysis who has increased blood calcium concentration and phosphorus concentration product.
Crack Stiffness Bone growth sensitivity (MPa) (a) (b) (c) Control apatite
7 112 7 2 7 Complex organoapatite 3 129 11 4 14 Note: Bone growth measured by fluorescence at (a) 355 to 425 nm, (b) 450 to 490 nm, and (c) 390 to 490 nm.
Briefly, the main stages of concentration start with three-stage crushing to 80% minus-16 mm, blending, grinding (in rod and ball mills) to 35% minus-74 micron, selective flotation, first of apatite
and then calcite concentrates, thickening and filtration.
The X-ray phase analysis confirmed that all the synthesized compounds were single-phase samples containing only apatite
phases, and no reflections corresponding to any impurity were detected (Fig.
present in minor amounts and usually forming grains < 0.
Source of trace elements in human body is via ingestion of food or on exposure to the environment, incorporated into the apatite
structure of the enamel.
Kwong Pui Ho (John Ho), Yangon, Myanmar, for assorted Ammolite, chrome tourmaline, hackmanite, thorite and ruby-in-quartz; rough amber, apatite
, corundum, gypsum, jadeite, mica, moonstone, pollucite and tourmaline; crystals of spinel and zircon; cabochons of hematite, kyanite, opal and pargasite; and faceted quartz, spinel and tanzanite.
In order to improve osseointegration various surface modification techniques such as plasma spraying , magnetron sputtering , acid and alkali treatments , bioactive hydroxyl apatite
coating , anodic oxidation  have been employed.
The composition provides an inhibition of bacterial adhesion to an apatite
test plate analyzed by scanning electron microscopy.
The coralline hydroxy apatite
replicated from the exoskeleton of porites [Coralline Hydroxy Apatite
Porites (CHAP)] consists of 230-[?
Scales and spines of different morphological groups and variable histologies of the genus Nostolepis have been selected for this purpose in order to compare data from fossil apatite
biomineral of different hard tissue structure and crystallinity, while avoiding any potential intertaxonomic bias.
