专利汇可以提供Gas detecting element专利检索,专利查询,专利分析的服务。并且PURPOSE: To detect gas with good sensitivity and purify the gas by providing multiple open cells to make a three-dimensional mesh skeleton structure and further coating gas detecting material with an insulating material.
CONSTITUTION: The gas detecting element S is formed by coating insulating material 7 and gas detecting material 5 on a heating element 1 composed of positive characteristic thermistor ceramics. The heating element 1 has multiple open cells 2 and has a three-dimensional mesh skeleton structure. This heating element 1 is obtained by forming a sponge-form molding and mesh-form molding with a synthetic resin such as, e.g., polyurethane, polyester, and polyether, or Japanese paper and the like, firing, e.g., BaTiO
3 and grinding the same to make fine powder, mixing this with water or binder to make a slurry and coating this slurry on the molding or depositing the same thereon and drying the same.
