SENSITIVITY CONDUCTIVITY OF THE CERAMIC ZNO WITH ADDITION OF SILVER TO METHANE
Journal Title: Сенсорна електроніка і мікросистемні технології - Year 2016, Vol 13, Issue 4
Abstract
Purpose of the paper was the experimental research of sensitivity of the electrical conductivity of ZnO ceramics with the addition of silver to the presence of methane in the air environment, and also obtained results were compared with data of gas sensitivity of ceramics to other hydrocarbons. It is shown that the conductivity of the ceramic has a sufficiently high sensitivity to methane and is comparable with the values for other gaseous hydrocarbons. Its increase can be achieved by adding silver into the ceramic additive that reduces its density. It found that the sensitivity of the leaned ceramics has a certain selectivity. This is detected by the displacement maximum of the temperature dependence of response to higher temperatures for the hydrocarbons with a higher molecular weight (propane, butane) in comparison with methane
