Abstract
U radu je prikazana priprema stabilne vodene suspenzije praha Al2O3 s dodatkom i bez dodatka otpadnog praha Al2O3 u udjelu od 20 % ukupne suhe mase praha. Udio suhog keramičkog praha u vodenoj suspenziji iznosio je 70 % mase. Nakon određivanja sastava stabilne suspenzije, vodene suspenzije su ulivene u gipsane kalupe. Dobiveni keramički sinterirani su u hibridnoj peći koja kombinira konvencionalno i mikrovalno zagrijavanje uzoraka. Na temelju provedenih mjerenja Arhimedove gustoće, izračunatog skupljanja i relativne gustoće te analiziranja mikrostrukture dobiveni su podaci i doneseni zaključci o utjecaju zamijene dijela čistog novog praha Al2O3 dodavanjem otpadnog praha Al2O3.
Abstract (english)
This Bachelor thesis presents the preparation of a stable aqueous suspension of Al2O3 (aluminium oxide) powder with a proportion of waste Al2O3 powder. The effect of replacing virgin powder with 20 % of waste powder was tested. Aqueous suspensions with 70 wt. % of alumina powders were poured into plaster moulds. The green ceramic bodies were be sintered in a hybrid furnace that combines conventional and microwave heating. Based on the measurements of the Archimedes density, calculated shrinkage and relative density, as well as the microstructure analysis, data on the effect of replacing a part of virgin with waste alumina powder were obtained and conclusions were drawn.
