NTK Zirconia Chip Heating Plate for Oxygen Sensor

NTK Zirconia Chip Heating Plate for Oxygen Sensor

Switching Plate Heating Core for Automotive oxygen sensor
Plate-Type Heating Core for automotive oxygen sensor are produced by implementing ceramic lamination processes. Due to the compactness, high power and rapid heating speed .Ceramic Heater can provide higher reliability than ever before. Mainly
applications include use as innovative types of heaters in the automotive, medical and semiconductor industries.

Process of Aluminum Ceramic Heater Element
1.Product matrix material use white alumina ceramic
3. a) Density ≥94 g/cm3；
4. b) Strength＞500 MPa。

2.Electrolyte material use YSZ electrolyte ceramic
5. a) Density ≥75 g/cm3；
6. b) Strength＞400 MPa；
7. c) Aging test: 230 ℃ × 50 h。

3.Electrodes, heaters, leads, pads all use Pt materials (Choose different Pt content material according to the function)

Engine Test
After the assembly of the product, then test the leak rate under the temperature of 25 ℃± 10 ℃ and the air pressure of 3.4 bar,
and the engine bench test is carried out under the condition that the leakage rate is less than 0.2 cm3 / min.NTK Zirconia Chip Heating Plate for Oxygen Sensor
