dc.description.abstract | Cordierite ceramic material, due to its properties such as low thermal expansion coefficient, low dielectric constant and high specific resistivity, could be used as an insulating material in high-frequency electronics. as well as a substrate for integrated circuits and electronic modules. In this paper, cordierite (2MgO center dot 2A1(2)O(3)center dot 5SiO(2)) was synthesized by the non-hydrolytic sol-gel process combined with solvothermal treatment starting from aluminium chloride, TEOS and magnesium chloride dissolved in absolute ethanol. Crystallization of mu-cordierite from gel occurred at temperatures between 900 and 1000 degrees C and a higher calcination temperature resulted in the transformation of mu-cordierite to alpha-cordierite. Cordierite material obtained by sintering of powder in the temperature range from 1400 to 1450 degrees C showed values of the dielectric constants from 7.93 to 3.78 and values of dielectric loss tangents from 0.049 to 0.001. | en |
