In present study, the Co0.7Zn0.3Fe2O4 ceramic was prepared using solid state reaction. The crystal structure of prepared ceramic indicated as solid solution. The SEM result indicated the dense structure of prepared ceramic as increased sintering temperature. For VSM result of Co0.7Zn0.3Fe2O4 ceramic indicated the super paramagnetic behavior with high magnetization. These results could lead us to the development of Co0.7Zn0.3Fe2O4 ceramic preparation optimized for specific applications.

Test Density and Porosity of rock have been done to see the relation to temperature influence 100 ᵒC, 200 ᵒC and 300 ᵒC. Rocks that will be tested first heated temperature with furnace tool then weighed with a digital balance. Density and Porosity measurement data were analyzed using Matlab Software with ASTMC373 equation. The result of Matlab in the form of graph shows average temperature change to Semurup rock density of 0.03 g / cm3 and the effect of temperature on Semurup rock porosity at 300 ᵒC is 30.29%. The average temperature change to Medang River rock density is 0.003 g / cm3 and the effect of temperature on Medang River rock porosity at 300 ᵒC is 0,55%. Looking at the rock crystal structure used XRD. Data from Characterization using XRD was analyzed with High Score Plus software. The result of rock characterization using XRD, from semurup showed that component of CaCO3 is 94%, crystal structure not yet fully formed and still in amorphous form, meanwhile rock from medang river show that component of CaCO3 is with 98%, crystalline structure have formed crystal.

On account of the increasing importance of the temperature factor in the theory of the analysis of crystal structure by means of X-ray reflection, and in view of the fact that no experimental work on the temperature effect has been published since the original preliminary investigation by Prof. W. H. Bragg in 1914, it is hoped that the present account will be of interest, in which the work of Bragg is extended to a variety of crystals and continuous temperature curves have been obtained ranging up to 950°C. Theories of the effect of temperature on X-ray reflection have been given by C. G. Darwin and P. Debye, and these agree in that the intensity of reflection— (1) Decreases as the temperature of the crystal increases; (2) Decreases more rapidly as the angle of reflection increases.

In present study, the structural and thermal characterizations of the natural material were investigated, the relationship between the crystal structure and thermal treatment were studied. The relationship between temperature and features of the crystal structure were determined qualitative by three conventional analysis techniques, X-Ray Diffraction (XRD), Energy Dispersive X-Ray Fluorescence (EDXRF) and Fourier Transform Infrared Spectroscopy (FT-IR). The results show that theBabylonia areolatahave a crystalline of calcium carbonate in phase aragonite, and the rice husks have amorphous structure. Another that, both sample annealed under air atmosphere, the effect of temperature induced both materials have phase transformation. Both sample transformed into oxide compound at temperature about 900C. In addition, the composition of both mineral and the level of the metals element were investigated by EDXRF. Functional group and chemical environment of silicon ions and calcium ions were identified by FT-IR, respectively.
