in a start powder mixture of magnesium zinc titanate and a barium lithium boro - silicate flux , it is discovered that the addition of lithium to the flux enables the manufacture of multilayer ceramic capacitors using the powder mixture , that perform to the cog standard including an accelerated life test . this addition of lithium also makes possible the sintering to maturity of cog multilayer capacitors at temperatures as low as 950 ° c ., which in turn allows the use of silver - palladium alloy buried electrodes of high silver and low palladium content which in turn lead to higher capacitor q and lower manufacturing costs .
