A method of producing a flat solid electrolyte layer of a flat film type oxygen sensor is disclosed. The method comprises in steps, (a) preparing first and second electrolyte pastes each containing stabilizer, the content of stabilizer in the first electrolyte paste being smaller than that in the second electrolyte paste, (b) applying the first electrolyte paste onto an electrode layer and then applying the second electrolyte paste onto the outer face of the first electrolyte paste to form a layered paste heap on the electrode layer, and (c) firing the layered paste heap to form a solid electrolyte layer on the electrode layer. With this production method, the stabilizer is uniformly and homogeneously distributed into the body of the fired electrolyte layer.
摘要:
A method of detecting numerical values for air/fuel ratio of either a lean air-fuel mixture or a rich mixture supplied to, for example, a combustion engine by means of an oxygen sensor disposed in the exhaust gas. The sensor comprises a porous measurement electrode layer on one side of a porous solid electrolyte layer, e.g., of zirconia and a porous reference electrode layer on the other side with a shield layer thereon, so that the reference electrode layer communicates with the exhaust gas through pores in the sensor. Measurement is accomplished by keeping a DC current flowing between the two electrode layers to establish a reference oxygen partial pressure on the reference electrode side. The intensity of the current is made below a critical value above which an EMF generated by the sensor becomes substantially constant unless the air/fuel ratio changes across the stoichiometric ratio, and the direction of the current flow is chosen depending on whether the air-fuel mixture is a lean one or a rich one.

Provided is an addition-curable silicone composition including A: a diorganopolysiloxane having a structure represented by a formula (1): (R1)(R2)2SiO((Ar)2SiO)nSi(R2)2(R1) (where R1 represents an aliphatic unsaturated group, R2 represents identical or different, unsubstituted or substituted monovalent hydrocarbon groups, Ar represents identical or different, unsubstituted or substituted aryl groups that may or may not contain a hetero atom, and n represents an integer of 1 or greater), B: an organosilicon compound containing at least two hydrogen atoms bonded to silicon atoms per molecule, and containing no aliphatic unsaturated groups, in an amount that is sufficient to cure the composition in the presence of the hydrosilylation catalyst described below, and C: a platinum group metal-based hydrosilylation catalyst. A cured product of this addition-curable silicone composition has superior transparency, a high refractive index, and favorable strength properties, and the composition can therefore be used as an optical element encapsulating material.
