Introducing two alkalis into the glass makeup significantly lowered the melting temperature, from 1500 to 1450°C, which effected changes in the properties of the glass. On introducing alkalis in amounts up to 5 mol.% the thermal linear expansion coefficient (LTEC) decreased from 58 to 50 (α × 10 – 7 K– 1) and the refractive index nD from 1.551 to 1.528. However, alkaline components adversely affect the hydrolytic resistance of the glass, transferring it from hydrolytic class I to II. The solution to this problem was to: (1) employ the polyalkaline effect, (2) maintain high radiopacity of the glass by introducing a small amount of highly effective radiopaque barium oxide into the makeup and significant strontium oxide reduction, and (3) increase the aluminum oxide content, which ordinarily increases the chemical resistance of the glass. The result was improved melting properties on lower melting temperatures and glass with high values of x-ray contrast (about 550%), light transmission (T = 90%), refractive index values nD = 1.530 and LTEC = 56 (α × 10 – 7 K– 1) were obtained while maintaining chemical stability with respect to water the corresponding hydrolytic class I.","PeriodicalId":579,"journal":{"name":"Glass and Ceramics","volume":"80 11-12","pages":"513 - 516"},"PeriodicalIF":0.6,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140810330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

YAG-precursor powders were obtained by chemical coprecipitation. The morphology and size of the agglomerates and crystallites were assessed by means of scanning electron microscopy, laser diffraction analysis, x-ray diffraction analysis, and Brunauer–Emmett–Teller gas adsorption. It was discovered that grinding of the YAG precursor powders can decrease the degree of agglomeration of the ceramic powder. It was found that with a mass ratio of grinding balls to precursor powder of 6.75/1 and a mass ratio of the grinding medium to the mass of the precursor powder of 4.5/1, optimal conditions obtain for providing the necessary granulometric characteristics and the highest mono-dispersity. In summary, by such means the properties of YAG optical ceramic can be improved by using of an additional grinding stage for the powders synthesized by chemical deposition and by selecting suitable grinding modes.","PeriodicalId":579,"journal":{"name":"Glass and Ceramics","volume":"80 11-12","pages":"479 - 486"},"PeriodicalIF":0.6,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140810331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As part of this investigation, YSAG:Cr optical luminescent ceramic was produced for the first time from ceramic powders of metastable compositions with a high content of scandium in the dodecahedral position. The compositions considered were described by the general formula Y3–xScxAl2–yScyAl3O12, where 0.12 ≤ x ≤ 1.50 and 0.08 ≤ y ≤ 1.00 p.u. [physical units] with total scandium content 0.12 – 1.70 p.u. The following investigations of YSAG:Cr ceramic samples were conducted: x-ray diffractometry, measurement of the shrinkage kinetics of ceramic compacts using dilatometry, and investigation of the morphology and elemental composition of the ceramic surface by means of scanning electron microscopy. The spectra of light transmission and luminescence were measured. It was shown that ceramic made from compositions with scandium content predominating in the dodecahedral positions reach maximum density at lower temperatures compared to compositions containing a larger amount of scandium in the octahedral positions. It was found that as the sintering temperature of YSAG:Cr ceramic increases, compositions with a high content of scandium in the dodecahedral position become unstable.","PeriodicalId":579,"journal":{"name":"Glass and Ceramics","volume":"80 11-12","pages":"464 - 471"},"PeriodicalIF":0.6,"publicationDate":"2024-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140810326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
