1 These apatite crystals are embedded in an organic matrix which is mostly collagen.

2 The main material of the phosphate fertilizer is apatite.

3 The Shangzhuang apatite deposit is a low - grade apatite deposit associated with Fe, vermiculitizated biotite and REE.

4 Apatite - wollastonite bioactive glass - ceramic ( AW GC ) has high biocompatibility and bioactivity and better mechanical properties.

5 Apatite, commonly seen as a blue or green transparent gem, is heated to produce electric blue colors like those found in Paraiba tourmalines.

6 It will be better if metal modified apatite is covered by photic organic film substantially.

7 Therefore, study on apatite crystal chemistry and mineralogical spectroscopy has both scientific significance and application values.

8 Secondly, relatively rich in mineral resources, coal, apatite, bauxite and other mineral exploitation were not.

9 Another apatite researcher, Francis McCubbin of the University of New Mexico, points out that one person's "bone-dry" could be another person's "relatively damp."

10 In this paper, the pelleting methods of natural apatite and the influencing factors are investigated.

11 Recent finds of Apatite in Madagascar have added to the popularity of this gem. Exhibiting excellent saturation, Madagascan Apatite's colors range from neon green to neon blue.

12 This concept has been used synthetically apatite - based biodegradable materials that can as artificial bone in humans.

13 A sedimentary rock consisting predominantly of apatite and other phosphates.

14 The treatment of wastewater containing lead with modified apatite was investigated.

15 Preparing apatite coating by the biomimetic synthesis process is a new developing trend to form bioceramic coating in recent years.

16 This paper introduces the process of biomimetic Methods : To prepare apatite coatings for different materials.

17 These findings suggested that local infection was the main cause of apatite stone formation; while hyperuricuria and acidification of urine contributed to the deposition of uric acid in the prostate.

18 Wadeite is paragenic with aegirine, nepheline, arfredsonite, microcline and apatite, and associated with natrolite, rinkite and cancrinite.

19 A kind of bacillus has shown significant ability to decompose apatite.

20 The films containing Ti - OH and negative charge are major reason to induce apatite.

21 On the basis of riddling various nonmetal minerals and the application test of bentonite, zeolite, apatite, vermiculite, glauconite, expanded pearlite etc.

22 Through late regional metamorphism, the phosphorite was turned into the apatite deposit.

23 Mn 2 + is suggested to bethe principal activator for CL in apatite.

24 Components of the stones included whewellite, weddelite, carbonated - apatite , struvite,[www.Sentencedict.com] brushite and uric acid.

25 Discussed in this paper is the mineralization of granitoid rocks based on SIMS data on trace elements and volatile components in apatite, zircon and biotite from granitoid rocks.

26 "I think we're dealing with a case of three blind men and an elephant," says James Greenwood, a planetary scientist at Wesleyan University in Connecticut who has worked on apatite studies.

27 Methods Standard IPT samples were prepared and immersed in a 1.5-fold simulated body fluid to coat bonelike apatite on IPT.

28 In the lower right corner is mineralized bony matrix containing the typical black CaPO 4 ( apatite ) crystals.

29 The deposit induced in the simulated body fluid ( SBF ) is bone - like apatite.

30 The high content of fluorine is closely related to the mixed-layer minerals of illite and smectite, apatite, hornblende , and K-feldspar.
