MANUFACTURING COMPOSITE ELECTROCERAMICS USING WASTE ELECTROCERAMICS
A method for manufacturing composite electroceramics comprises obtaining sintered electroceramic waste material. The waste material is grinded to obtain first ceramic powder having a particle size of 10-400 micron. The first ceramic powder is mixed with NaCl, Li2MoO4 or other ceramic powder having a particle size of 0.5-20 micron, in a ratio of 60-90 vol-% said first ceramic powder and 10-40 vol-% NaCl, Li2MoO4 or other ceramic powder. The obtained ceramic powder mixture is mixed with aqueous solution of NaCl, Li2MoO4 or said other ceramic, in a ratio of 70-90 wt-% the ceramic powder mixture, and 10-30 wt-% the aqueous solution. The obtained homogeneous mass is compressed in a mould for 2-10 min in room temperature and in a pressure of 100-400 MPa. The compressed homogeneous mass is removed from the mould, thereby obtaining electroceramic composite material. Alternatively to the use of the water soluble salt an organometallic precursor compound can be used.
