Silicijev nitrid, ki vsebuje ?$Al_2O_3$?, MgO in majhne količine kovinskega silicija kot aditiva za sintranje, smo sintrali pri temperaturah 1650°C in 1700°C pod povišanim tlakom dušika in vzorce zadrževali pri temperaturi 1400°C do 12 ur. Študirali smo morfologijo kristalov?$\beta-Si_3N_4$? v gosto sintrani keramiki in njen vpliv na velikost upogibne trdnosti. S kvantitativno analizo mikrostrukture zlomnih površin smo pokazali, da imata v gosto sintrani ?$Si_3N_4$? keramiki velikost in porazdelitev velikosti paličastih zrn ?$\beta-Si_3N_4$? največji vpliv na upogibno trdnost pri sobni temperaturi. Po postopku sintranja v visokotemperaturnem avtoklavu smo izdelali vzorce rezalnih nožev in kroglic</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-I1Z40L2O"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-I1Z40L2O" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-I1Z40L2O/3c2d9389-c666-46a9-8bb2-f03513e41031/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:dataProvider xml:lang="en">National and University Library of Slovenia</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-I1Z40L2O/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-I1Z40L2O" /></ore:Aggregation></rdf:RDF>
