The crystal structures were determined by single-crystal X-ray diffraction and powder neutron-diffraction (Ce4[Si4O4N6]O and Sr3Pr10Si18Al12O18N36). Ce4[Si4O4N6]O represents the first hyperbolically layered silicate. The Si/O/N network is built up of Q3 type SiON3 tetrahedra enveloping the large [Ce4O]10+ cations. The sialons Sr3Ln10Si18Al12O18N36 contain a complex network of corner sharing SiON3, SiN4, and AlON3 tetrahedra, while Sr10Sm6Si30Al6O7N54 is built up by a capped double-layer structure of SiON3, SiN4, AlON3, and AlN4 tetrahedra. The crystallographic ordering of Al/Si and O/N, respectively, was investigated by refinement of the neutron powder diffraction data and lattice energy calculations (MAPLE) on the basis of the single-crystal X-ray diffraction data.

Recently combinatorial approaches have been made to the screening of superconductive, magnetoresistant and photoluminescent materials [Angew. Chem. Int. Ed., 38(17) (1999) 2494]. Although the development of multicomponent hard coatings by a combinatorial approach could lead to a significant decrease in cost and time, to our knowledge, no paper has been published in this field up to now. In this paper, the deposition and characterization of laterally graded (Ti,Al)N hard coatings with compositions from nearly pure TiN to AlN is presented. The coatings have been deposited by reactive magnetron sputtering, using an aluminum and a titanium target at a low angle to the substrate surface as well as a system of apertures. The relation between composition and oxidation resistance of the ternary films has been investigated. The results illustrate that the combinatorial approach is a powerful and cost effective tool for the development and optimization of new materials for hard coatings.</div>","PeriodicalId":100700,"journal":{"name":"International Journal of Inorganic Materials","volume":"3 8","pages":"Pages 1181-1184"},"PeriodicalIF":0.0,"publicationDate":"2001-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1466-6049(01)00121-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73502476","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}

Hole-doping was carried out by means of high-oxygen-pressure annealing at 600°C under a pressure of 400 atm (20%O2+80%Ar at a total pressure of 2000 atm) using a hot-isostatic-pressing (HIP) furnace. In order to realize metallicity, a prolonged HIP-treatment for about 22 days or more is required. However, this annealing period is reduced to about 5–6 days, when the crystals are grown from the starting charges containing Ag in the form of Ag2O. Even in the as-grown state, the measured room-temperature resistivity is about two to three orders of magnitude lower than that of La2Cu2O5 crystals grown from charges without silver. The results show that the silver addition facilitates the oxygenation of the La2Cu2O5 crystals.</div>","PeriodicalId":100700,"journal":{"name":"International Journal of Inorganic Materials","volume":"3 8","pages":"Pages 1201-1203"},"PeriodicalIF":0.0,"publicationDate":"2001-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1466-6049(01)00127-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83774199","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}
