Abstract
A gas-sensing material for detecting the presence particularly of hydrocarbon gases which is characterized by being formed of a sinter containing 20 to 99.85 mol % of ZnO, 0.1 to 50 mol % of MgO and 0.05 to 30 mol % of Me.sub.2 O.sub.3 (Me denotes at least one element selected from the group consisting of gallium (Ga), boron (B), indium (In), iron (Fe), aluminium (Al) and chromium (Cr)), or another sinter prepared by blending 0.01 to 10% by weight of platinum (Pt) to the above-mentioned composition.
Claims8
A gas-sensing material which comprises a sinter consisting essentially of 20 to 99.85 mol % of ZnO, 0.1 to 50 mol % of MgO and 0.05 to 30 mol % of Me.sub.2 O.sub.3 wherein, Me is at least one element selected from the group consisting of gallium, boron, indium, iron, aluminum and chromium.
