Using calcium hydroxide as raw material in organic system, high-purity diphenylpropylene glycol calcium complex was obtained by complex reaction, recrystallization and vacuum high temperature decrystallizing water, and then high-purity anhydrous calcium fluoride was prepared by reaction of the complex with ammonium hydroxide. By differential thermal analysis, transmission electron microscopy, X-ray diffraction, inductively coupled plasma mass spectrometry and oxygen analyzer, the prepared calcium fluoride was analyzed and characterized. It was proved that the method can obtain calcium fluoride with high-purity, anhydrous, low oxygen content and high crystallinity. Effectively avoiding the problems of harsh reaction conditions, easy introduction of impurities by traditional “dry” preparation process, and high oxygen content and difficult filtration of products by traditional “wet” preparation process. It is a green, efficient and novel preparation method, which provides a new method and idea for the preparation of high purity fluoride salt.","PeriodicalId":18218,"journal":{"name":"Material Sciences","volume":"15 04","pages":"614-621"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pdf.hanspub.org/ms2025154_91281883.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this awareness has not been accompanied by a commensurate development of policies and legislation to protect these resources. This lacuna has resulted in an escalating problem of water pollution, which has deleterious effects on human health, and can even prove fatal. The heavy metal ion Cu2+ poses a grave threat to human health and ecosystem stability, thus garnering significant attention from governments worldwide. The removal of pollutants from water is an area of significant research, with a range of treatment methods in existence. Among these, adsorption has been shown to be effective in the removal of dyes and heavy metal ions from wastewater, due to its low cost, simple preparation, and high efficiency of treatment. The preparation of the CMCS/MH composite aerogel adsorbents was undertaken via the freeze-drying method, and subsequent characterisation tests were conducted. It was established that the water resistance of the composite adsorbent exhibited an increase with the increase in the introduction of MH. However, when the amount added was excessive, agglomeration occurred, resulting in a deterioration of water resistance. Adsorption experiments were conducted to investigate the alterations in the adsorption capacity of the CMCS/MH composite adsorbent in the adsorption of Cu²⁺ under the influence of various factors, including pH, adsorbent amount, and temperature. The adsorption kinetics and thermodynamics were modelled during the adsorption process. The findings indicated that the most effective adsorption outcome for Cu²⁺ was attained when the amount of MH was incorporated as C8M2.","PeriodicalId":18218,"journal":{"name":"Material Sciences","volume":"15 05","pages":"946-957"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pdf.hanspub.org/ms_1281925.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147918167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanical properties, friction and wear properties, density and conductivity of Al2O3 reinforced Al70Fe10Cu20 alloy were detected by X-ray diffractometer, tensile testing machine, Vickers hardness tester, friction and wear testing machine, density meter and conductivity meter. The results show that the addition amount of Al2O3 particles and the distribution uniformity of Al2O3 particles in Al70Fe10Cu20 alloy after vacuum melting have a great influence on the microstructure and properties of the composite material. The optimal addition amount of Al2O3 is 0.1 wt% based on various performance indicators.
