MANUFACTURING COMPOSITE ELECTROCERAMICS USING WASTE ELECTROCERAMICS
A method for manufacturing composite electroceramics comprises obtaining recycled capacitors, coils, resistors, conductors circuit boards, and/or other recycled electronic components. The components may be grinded into a particles having a particle size below 2 mm, and mixed with NaCl powder or Li2MoO4 or other watersoluble ceramic powder having a particle size of 5-200 microns, in a ratio of 10-40 vol-% optionally grinded components, and 60-90 vol-% NaCl powder or Li2MoO4 or other ceramic powder. The obtained solids mixture is mixed with aqueous solution of NaCl, Li2MoO4 or said other ceramic, in a ratio of 70-90 wt-% solids mixture, and 10-30 wt-% aqueous solution. The obtained homogeneous mass is compressed in a mould for 2-10 min, in room temperature, in a pressure of 100-400 MPa. The compressed 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.
