    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). The results of charactdrzations how that opimum ratio in nrassc or{rosition of CUO and ZnO is 95Vo:5o/aot 1000'C temperatureI.t hast he highestd ensi'tyo f 9.205 g/cm3w hile the highesto f conpressive strength is 218.79 MPa" the highest har&ress is 1816.920 MPa and nnrphological structures are evenlv distributed.
