Capacitive microelectronic components on the basis of the composite materials

BaTiO/sub 3/- ceramic is one of the most important dielectric materials. Optimal sample properties for capacitive ceramic are obtained by isothermal sintering of barium titanate at 1380/spl deg/C/240 min. The possibility prognosis of composite dielectric material composed of a barium titanate and novolac (phenolformaldehyde) are examined, especially from the standpoint of their application in the technology as capacitors. Here, BaTiO/sub 3/ phase in the form of particle size less than 100 /spl mu/m is dispersed in homogenous organic matrix materials. Variation of some composite properties by change in volume ratio ceramic powder, and change of dielectric constant and microstructure of composite are examined. Above mentioned allow to establish the appropriate electrical model of corresponding electrical component was formed.
