Barium Hexaferrite is a permanent magnet material known for its excellent quality and relatively inexpensive manufacture. Barium hexaferrite has good stability and can be applied in various technologies. In this research, the synthesis of barium hexaferrite has been successfully made from the primary materials Fe (NO3)3 and Ba (NO3)2 using the sol-gel method, as well as other materials such as NaOH, chitosan, molasses, acetic acid and distilled water as the primary solvents for several materials. In addition, variations in aging time 0 hours, 2 hours, 4 hours and 6 hours were added to see the effect on morphology, crystal structure and the magnetic properties of barium hexaferrite magnets. The characterization process is carried out with three testing processes, namely X-Ray Diffraction testing (XRD), Scanning Electron Microscopy (SEM) and Vibrating Sample Magnetometer (VSM). From the XRD, it was found that the desired phase of Barium Hexaferrite (BaFe12O19) was formed, while in the SEM testing process, it was seen that the aging time of the barium hexaferrite sample decreased the particle size of the barium hexaferrite BaFe12O19 from an aging time of 0 hours seen 681.459 nm and at an aging time of 6 hours. Visible 538.859 nm particle size formed. The VSM characterization results showed that different aging times did not affect the barium hexaferrite nanomagnets' magnetic properties.

BaCO3 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, NH4OH 65% so that the deposition process is faster and aquades as a neutralizer.
