Abstract

PURPOSE: To make an element highly sensitive not to alcohol gases but to isobutan gases thereby to enhance reliability by containing a preset quantity of noble metal catalyzer and P in a semiconductor of reducing type metal oxide.
CONSTITUTION: A semiconductor material of reducing type metal oxide is mixed with water or a binder. Pt, Pd or Rh is added thereto at wt. patio of 0.005 to 8% as a solution of a suitable compound. To the aforementioned noble metal catalyzer, there is added 1.5 to 30 times (or 0.05 to 30 times in case the simple substance Pd is used) of P in the form of an inorganic compound of P to prepare a gas-sensitive material 3 of paste state having suitable pH and viscosity. This material 3 is applied and dried to a tubular insulating substrate 1 which is equipped with a pair of electrodes 2. After that, the product is sintered at 300 to 1100°C thereby to provide a gas element 4 for LPG.
