The technology we developed consists of the following four processes: Process (1) is the initial acid elution; Process (2) involves alkali precipitation; Process (3) is the second acid elution; and, Process (4) utilizes ion-exchange. In Process (1), the addition of DPR slag to 0.5 M of a nitric acid solution for 24 min resulted in sufficient phosphorus dissolution. In Process (2), ammonia was added to the dissolved solution, and phosphorus was precipitated with high efficiency. The timing of the addition of ammonia significantly influenced the removal of silicon and iron, which would have been inconvenient to accomplish in subsequent processes. In Process (3), the precipitation obtained in Process (2) was re-dissolved in a nitric acid solution. The dissolution of phosphorus together with other elements progressed sufficiently, and we confirmed that silicon could be completely separated as silica by using high-concentration nitric acid at this stage. The fact that silicon could be removed during Process (3) was an important finding, since silicon could not have been separated in the Process (4). In Process (4), by passing the phosphorus-containing solution obtained in Process (3) through an ion exchange resin, elements other than phosphorus and silicon could be removed, which confirms that the range of applications for this technology could be expanded.","PeriodicalId":20022,"journal":{"name":"Phosphorus Research Bulletin","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135267990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, it was shown that the addition of CNF-P promoted the formation of both micron-sized pores and macro-sized pores (100-400 μm).

The whitlockite structure can incorporate metal ions, which enables the introduction of antibacterial and antiviral agents such as copper ions. The present study describes the synthesis of copper whitlockite (CuWH) via a single-step hydrothermal transformation of calcium hydrogen phosphate dihydrate in the presence of copper ions. Hexahedral morphology of single-phase CuWH was synthesized at 220 °C for 12 h at pH 2.0 in the presence of 5 to 7 mol% Cu 2+ ions, suggesting that CuWH precipitation was both dose- and pH-dependent. The CuWH structure contained protonated phosphate, which also suggests that Cu 2+ ions were incorporated not only into the Ca(5) site but also the Ca(4) site. The dissolution test mimicking a bioresorption environment created by osteoclasts showed similar dissolution characteristics of Ca 2+ and Cu 2+ ions in acetic acid–sodium acetate buffer solution containing potassium nitrate at pH 5.5.","PeriodicalId":20022,"journal":{"name":"Phosphorus Research Bulletin","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80971689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have previously developed porous hydroxyapatite ceramics, containing bone minerals (bone HAp). These ceramics showed great bone-forming ability and bio-resorbability; however, their mechanical strengths were in sufficient for clinical application. Thus, we focused on the refinement of raw material powder to improve the strength of the resulting bone HAp ceramics. In particular, we clarified the effect of ball milling time on sinterability of the bone HAp powder. Among the prepared samples, the most easily sinterable powder was prepared after ball milling for 1 hour. This powder showed the smallest particle size with a particle size distribution that was close to a uniform distribution. The compressive strengths of Bone HAp ceramics from powders prepared by ball-milling for 30 minutes and 1 hour were of 55.7 MPa and 63.1 MPa, respectively.
