Study on Methane Adsorption Capacity of Sensor Probe Based on Lead-Free Piezoelectric Resonance Modified by Zeolite X Jie Du1,*, Huiling Du2 and Qunli An3 1,2,3College of Materials Science and Engineering, Xi'an University of Science and Technology, Xi'an, 710054, China *hldu@foxmail.com Keywords: Lead-free Piezoelectric Ceramics, Piezoelectric Resonance, Zeolite X, Sensor Probe, Methane Adsorption Abstract.
NBT), a kind of A - substituted perovskite type compound, is considered a promising candidate for lead-free piezoelectric materials because of its high piezoelectric and ferroelectric properties.
After the micropore is filled, the adsorption behavior occurs on the external surface of the material, which is similar to that of macroporous and mesoporous materials.

Due to the influence on fire extinguishing efficiency and reliability which cause by arrangement and selection of sprinklers, many reference materials have carried on deep discussions and propose their own views on sprinklers arrangement [1-8].
