Stabilization of amorphous calcium phosphate in the structure of hydroxyapatite during liquid-phase synthesis

Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов
Amorphized hydroxyapatite with stabilized inclusions of amorphous calcium phosphate was obtained by a wet synthesis at pH 11. Reliable indicators of the presence of amorphous calcium phosphate in the hydroxyapatite structure includes: 1) peaks of α ...

Prospective randomised controlled trial comparing PLLA and PLDLA/HA/β‐TCP interference screws in anterior cruciate ligament reconstruction: CT scans, MRI and clinical outcomes

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Modifying interference screw composition may ensure better osteoconductive properties in order to reduce tunnel enlargement after anterior cruciate ligament (ACL) reconstruction. The primary and secondary purposes were to evaluate tunnel and screw volume changes in poly‐L‐lactide acid (PLLA) and poly‐D‐lactic acid + hydroxyapatite + β ...

Tricalcium Phosphate-Trimagnesium Phosphate System

The Journal of the Society of Chemical Industry, Japan, 1958
苦土を含む溶成リン肥の基礎研究として,従来全く報告のないリン酸三石灰-三苦土系の状態図を作製し,各相の性質を明らかたした。リン酸三石灰の石灰の少部分を苦土で置換するとリン酸三石灰のβ 変態が安定化し,格子の縮小,ク溶率の低下が起り,高温でもα 変態に転移し難くなる。石灰の1/6～1/2が苦土で置換された組成では,溶融状態からまずβ-リン酸三石灰が晶出するが,ついで1175℃ で融液との間に包晶反応が起って,新発見の化合物,Ca3Mg3(PO4)4が生成する。これよりも苦土の多い範囲では,この化合物とリン酸三苦土が生成する。この化合物は溶成苦土リン肥,リン酸三苦土とも溶解性が似ており,2%クエン酸にはよく溶けるが,中性クエン酸アンモンにはあまり溶けない。

Tricalcium Phosphate and its Variation [PDF]

Bulletin of the Chemical Society of Japan, 1958
Abstract Properties of tricalcium phosphate and effects of many other ingredients upon the structure and solubility of the phosphate were investigated. By the reaction of calcium salts with phosphates in aqueous solution, tricalcium phosphate hydrate with a definite structure is not formed but hydroxy apatite with an excess of phosphoric

Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

steel research international, EarlyView.
The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...

Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

Archaeometry, EarlyView.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...
