Sparingly soluble minerals such as apatite Ca 5 PO 4 3 F OH fluorite CaF 2 calcite CaCO 3 sheelite CaWO 4 magnesite MgCO 3 and barite BaSO 4 are hydrophilic selective hydrophobization of the desired mineral by various reagents is critical in determining the effectiveness of the separation separation of sparingly soluble
A plasma and precursor assisted biomimetic process utilizing plasma and alternate dipping treatments was applied to a Leed Keio artificial ligament to produce a thin coating of apatite in a supersaturated calcium phosphate solution Following plasma surface modification the specimen was alternately dipped in calcium and phosphate ion solutions
The most extensive amount of REE substitution into igneous apatite up to 27 wt % REE 2 O 3 has been reported from the Ilímaussaq complex in South Greenland Rønsbo 1989 Rønsbo 2008 The Ilímaussaq complex is a textbook example for the essentially closed system evolution of an alkaline plutonic system Larsen and Sørensen 1987 Marks and
The isoconversional model allows to take into account this phenomenon Applying this model to the process occurring in domain 3 led to straight lines representing ln t as functions of 1/ T for various values of the conversion rate as in Figure 10 The deduced activation energy E a values allow to draw the latter quantity as a function of X
When recycled water containing high levels of dissolved salts and metal ions is used in the process of apatite flotation the recovery and P 2 O 5 content can be seriously affected However single treatment technologies often have problems such as high energy consumption secondary pollution and a poor treatment effect when treating real
This process is believed to be directed by highly acidic non collagenous proteins6 7 9 10 11; however the role of the collagen matrix12 13 14 during bone apatite mineralization remains unknown

Extremely light apatite δD values indicate deep originated water in intracontinental granites and basalts from the North China Craton probably from a stagnant slab within the mantle transition zone
Bone is a complex and structured material; its mechanical behavior results from an interaction between the properties of each level of its structural hierarchy The degree of mineralization of bone bone density measured at tissue level and the characteristics of the mineral deposited apatite crystals are major determinants of bone strength Bone remodeling
The phosphate ore flotation is achieved through the surface electrical behavior difference among apatite dolomite and quartz but it is usually affected by the dissolved ions from pulp especially Ca2 and Mg2 The zeta potentials of apatite dolomite quartz and phosphate ore in different solutions were measured to discuss the surface electrical behaviors of them in this study It
The Power of Apatite Gemstagram Furthermore apatite also contains phosphorus which is required for healthy nerve tissue genetic building block function correct utilization and storage of energy filtration of waste from kidneys and bone growth Not only that but it also helps in the elimination of free radicals thus slowing the aging
Alternatively the inclusion of fission track data of natural samples that have experienced approximately constant heating for millions of years in the fitting process has been proposed to help
A plasma and precursor assisted biomimetic process utilizing plasma and alternate dipping treatments was applied to a Leed Keio artificial ligament to produce a thin coating of apatite in a supersaturated calcium phosphate solution Following plasma surface modification the specimen was alternately dipped in calcium and phosphate ion solutions
Metallic Ceramic and Polymeric Biomaterials K Ishikawa in Comprehensive Biomaterials 2011 Fast Setting Apatite Cement Apatite cement consisting of TTCP and DCPA has become clinically available However original apatite cement took 30 60 min to set even though the combination of large TTCP and small DCPA was employed Setting time of 30 60 min is
