| titleOfInvention | A kind of preparation method of lanthanum strontium manganese oxygen/zinc oxide aluminum complex phase ceramic |
| abstract | The present invention relates to a kind of lanthanum strontium manganese oxygen/zinc oxide aluminum complex phase ceramic preparation methods.Specifically: lanthanum strontium manganese oxygen powder being made using solid reaction process first；Then lanthanum strontium manganese oxygen powder and zinc oxide aluminum powder are weighed respectively, is put into planetary ball mill, are uniformly mixed；Mixed powder is placed in plasma activated sintering furnace and is sintered, sintering condition are as follows: 1000~1200 DEG C of sintering temperature, 3~15min of soaking time, 10~50MPa of sintering pressure finally obtain lanthanum strontium manganese oxygen/zinc oxide aluminum complex phase ceramic.The present invention adds the second phase of semiconductor oxide zinc-aluminium powder, utilize interfacial effect, conductive channel and the good sintering aids role between its optimization and lanthanum strontium manganese oxygen matrix grain, the low field magnetoresistance of lanthanum strontium manganese oxygen ceramics near room temperature, magneto-resistor >=14% under 0.5T downfield can be obviously improved.Plasma activated sintering technique is used simultaneously, realizes the fast densified sintering (consistency > 96%) of lanthanum strontium manganese oxygen/zinc oxide aluminum complex phase ceramic low temperature. |
