Chip for chip-type non-heating oxygen sensor and preparation method
The invention discloses a chip for a chip-type non-heating oxygen sensor, which comprises a solid electrolyte ceramic layer, an outer electrode arranged on the upper surface of the solid electrolyte ceramic layer, and an inner electrode and a gas channel which are arranged on the lower surface of the solid electrolyte ceramic layer, and is characterized in that the outer electrode comprises an outer lead electrode part and an outer catalytic electrode part which are formed by two times of firing, and the outer lead electrode part and the outer catalytic electrode part are of a split structure.The chip is simple in structure and convenient to produce and process, the production cost is greatly reduced, the chip is suitable for large-batch automatic production, and the outer catalytic electrode part adopts a non-co-firing process, so that good low-temperature starting performance of the chip is guaranteed.
本发明公开了一种片式非加热型氧传感器用芯片，包括固体电解质陶瓷层、设置于所述固体电解质陶瓷层上表面的外电极、及设置于所述固体电解质陶瓷层下表面的内电极与气体通道，其特征在于：所述外电极包括两次烧制形成的外引线电极部分与外催化电极部分，所述外引线电极部分与所述外催化电极部分为分体式结构。该芯片结构简单，生产加工方便，大大降低了生产成本，适用于大批量自动化生产，且外催化电极部分采用非共烧工艺，保证其具有良好的低温启动性能。
