Fabrication of Ceramic CompositesB asedo n CUO-ZnO

Abstract

CUO-ZnO ceramic corrposites have been obtained by pessing conventional method. The composite materials are CUO and ZnO powders with ratio in mass conposition of CuO and ZnO are7 5o/o:25Y8o0, o/o:2ff/o8, 5Yo:t5o/o9,0 Yo:l0%oa nd9 5o/o:5o/Toh. e samplesw ere made by three steps. The first step, CUO and ZnO powders are sieved with particle size of 100 mesh. Theq both of powders are mixed until homgeneous for 5 minutes with dry mixing method. The second step, the bomgeneous powders are fab'ricated with pressure at 300 MPa for 10 minutes to form a pellet. The last step, the pellet was burned by furnace at tryeratures 80(PC, 90ffC and 100fC for 3 hours. Each sample that has been burned was characterized by physical properties (densrty), morphological analysis (SEM), mechanical properties (conpressive strength and hardness) and crystalline structural analysis CXRD).
