Sažetak
Gusta keramika se dobija iz pepela iz REK Bitola u Republici Makedoniji. Predmet ovog istraživanja su četiri tipa pepela iz elektro filtera i jedan tip sa deponija sa česticma manjim od 0,063mm. Konsolidacija se postiže pod pritiskom (p = 133 MPa) i sinterovanjem (na temperaturama 950, 1000, 1050 ili 1100 ° C ibrzinom zagrevanja od 3 ili 10 ° C/min). Zgušnjavanje se postiže sinterovanjem tečnom fazom i reakcijom u čvrstom stanju, pri čemu se formira diopsid (Ca(Mg,Al)(Si,Al) O ). Keramika optimalnih karakteristika (poroznosti 2,96ˆ,5%, jačine savijanja 47 ± 2 MPa, čvrstoće 170 ± 5 MPa) je dobijena na1100 ° C brzinom zagrevanja od10 ° C/min.
