Carbonate apatite (CO 3 Ap) is a biomaterial mainly used as bone graft. Commonly used carbonate apatite is now microsized, although the application of nanoparticle materials is already widely used. Nanoparticle fabrication can be done through milling process using bead mill. The aim of this study is to evaluate particle size of nano carbonate apatite fabricated using bead mill.
Calcium apatite is a mineral commonly used in fertilizer and is also a major component of bones and teeth. The researchers formed a "sponge" in the ground by injecting two inexpensive and nontoxic chemicals, calcium citrate and sodium phosphate, into a well especially designed for injecting solutions underground at the former uranium mill.
characterristics of apatite used for the adsorption were as follows: average content of P 2O 5: 14.3 %, particle size: 0.074 mm. b) apatite concentrate (natural apatite was pre-pared with the procedure of flotation and concen-tration, and then treated by the process of magnetic separation in order to obtain high quality apatite con-centrate.
Purpose Chemical stabilization (or immobilization) is an in situ remediation method that uses amendments to reduce heavy metals availability in contaminated sediments. In this study, stabilization of heavy metals (Pb, Cd, Zn, and Ni) in contaminated marine sediment was conducted using three amendments (i.e., red mud, apatite, and a red mud/apatite composite) …
Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite. (These biological Apatites are almost exclusively the Hydroxylapatite type.) Chemical Formula.

1. Introduction. Hydroxyapatite (HAp) is widely used in biomedical applications, especially in orthopaedic, odontology, as well as a coating material for metallic implants .HAp is made up of 70% bone, while collagen comprises of 20% and water makes up 10% .HAp has a chemical formula of Ca 10 (PO 4) 6 (OH) 2 instead of Ca5(PO4) 3 (OH) because it contains …
Apatite geochemical and Sr Nd isotopic compositions provide robust means for constraining a wide range of geological processes in earth and planetary sciences, including magmatism, metamorphism, metasomatism, planetary geochemistry, and geochronology. Here we extend the utility of these data to fingerprint magmatic evolutionary processes and granitoid …
Introduction. The use of 3-dimensional (3D) scaffolds is an approach of bone tissue engineering for the reconstruction of massive bone defects such as diseased or damaged bones (Karp et al., 2003).Scaffolds should be biocompatible and provide a temporal and spatial three-dimensional framework to form the designed tissues; also, they should act as an artificial …
Pneumatic Conveying Design Guide. David Mills. Elsevier, Oct 21, 2003 - Science - 650 pages. 2 Reviews. The Pneumatic Conveying Design Guide will be of use to both designers and users of pneumatic conveying systems. Each aspect of the subject is discussed from basic principles to support those new to, or learning about, this versatile technique.

Drum Mill TM 500. The Drum Mill TM 500 is a laboratory ball mill designed to grind large sample volumes up to 35 l. It accepts initial feed sizes of up to 20 mm and can achieve grind sizes down to 15 µm by friction and impact. Hard, brittle or fibrous samples are pulverized in the 150 l drum filled with 80 kg grinding balls.

Apatite – raw. $ 2.50. When used for spiritual reasons, apatite can be used to assist one in the development of deeper states of meditation and to stimulate clairvoyant abilities. It is good for inner-clarity, peace and for raising Kundalini energy. Apatite is a stone of creativity and is used to awaken the higher self.
PNNL will evaluate the apatite barrier in laboratory studies. If the laboratory studies indicate the apatite will hold uranium we will move on to field studies at the DOE's Uranium Mill Tailings Remedial Action field site near Rifle, Colorado," Rigali said. Another potential application is the remediation of Hanford tank waste.
