| titleOfInvention | Chip type oxygen sensor and preparation method thereof |
| abstract | The invention provides a chip type oxygen sensor and a preparation method thereof. A porous protection layer of the chip type oxygen sensor comprises a transition layer, a porous layer and an absorption layer; holes are formed on all the layers, so that the bottom of the porous protection layer is communicated with the top of the porous protection layer; the holes on the transition layer with the diameters ranging from 0.1mu.m to 1.5 mu.m account for above 80 percent of the total holes on the transition layer; the holes on the porous layer with the diameters ranging from 0.3 mu.m to 8 mu.m account for above 80 percent of the total holes on the porous layer; the holes on the absorption layer with the diameters ranging from 0.1 mu.m to 2 mu.m account for above 80 percent of the total holes on the absorption layer; the transition layer contains zirconium oxide with stable yttrium oxide and magnesia-alumina spinels; the porous layer contains zirconium oxide, magnesia-alumina spinels and noble metal; and the absorption layer contains magnesium oxide, calcium oxide, aluminum oxide, magnesium sulfate and barium oxide. Compared with the prior art, the chip type oxygen sensor has the advantages of high sensitivity and thermal shock resistance and long service life. |
