ABSTRACT:
A low-fire ceramic composition and a process for manufacturing ceramic articles using such a composition. The ferrite composition containing a mixture of finely divided particles of 0.1-2 wt % of V.sub.2 O.sub.5 and 99.9-98 wt % of Ni--Cu--Zn ferrite can be densified at an ultra-low temperature of 850-900.degree. C. to form a ceramic ferrite body having a sufficient sintered density. The ferrite composition can be processed with organic solvents, polymeric binder and plasticizer to produce an unfired green tape which is cofirable with high electrical conductivity metallurgies such as silver to produce multilayer ceramic inductor devices.
