BaCO 3 with natural iron sand is the basic material for making samples of Barium M-Hexaferrite (BaM) which is doped to make the utilization of BaM more effective by adding metal ions that have almost the same size as cobalt (Co), copper (Cu), and Zinc (Zn) and using the coprecipitation method. The process of making Barium M-hexaferrite is carried out in the advanced and basic chemistry laboratory, FMIPA University of Mataram. In this study, variations in concentration and temperature variations during the calcination process were used, namely (x = 0.0; 0.4; 0.8; 1.0) (T = 200; 600; and 1000 °C). These variations greatly affect the sample, where the greater the concentration and temperature of calcination, the color produced in the sample will be darker and this is by the purpose of the calcination process carried out, namely the greater the temperature at the time of calcination, the more water content in the sample will be. reduced because the solvent in the sample evaporation occurs. In addition to these materials, the solvent used also plays an important role in the sample-making process, namely using HCl37% to dissolve, NH 4 OH 65% so that the deposition process is faster and aquades as a neutralizer.
