IDEA #62XWUC Sensor Material Responsive To Ethanol And Acetone Vapors

Areas of Application The material is to be used in gas sensitive elements of chemical sensors for measuring concentration of organic compound vapors in the air Specifi cation The material consists of doped SnO2 crystalline powder with a particle size of 10÷30 nm. The sensor elements are made using the thick fi lms technology. Sensitive to ethanol and acetone in the air at concentration, ppm Temperature range, °С Response time of sensor model signal (depending on gas concentration), s Time of return to the original settings after measurement, min 0.5-100 ≥200 10-20 5-10 IPR Protection IPR3 Advantages The stability of material properties is explained by its unique physical and chemical composition that is a result of using the patented synthesis method in which SnO2 nanoparticles are formed and crystallize rapidly and simultaneously at a low temperature. For comparison, commercial SnO2 is obtained in the amorphous state, using a long-term heat treatment at 600÷700 °C, which impairs the sensory properties of the material Stage of Development. Suggestions for Commercialization IRL3, TRL3 Upon request, sensor material samples are produced, information on particle size, element and phase composition, crystal structure, and technical parameters measured by model sensors of organic compound vapors in the air are provided
