Abstract
PURPOSE: To obtain the detector that is small-sized and cheap and its characteristic is stable, by using porous ceramics, which have through holes and possess specified porocity and a specified, mean, porous diameter, as a protective cover of the detector.
CONSTITUTION: Porous ceramics, which have through holes and possess 30W60% porocity and 1W300μ mean, porous diameter, are mounted to an inflammable gas detector as the protective cover. A cylindrical protective cover 1 of porous ceramics as mentioned above is provided in such a manner that aluminium oxide and silicon oxide are employed as materials, and an organic binder is added to the materials, mixed and granulated, press molded and sintered by means of an electric furnace. A semiconductor type gas detector consist a gas detecting element 2, a heating element 3 and lead wires 4 by making use of such a protective cover 1. The porous ceramics with arbitrary characteristics within a range of 20W70% porocity and 0.5W1000μ the mean, porous diameter can be prepared by changing the quantity of the organic binder added and a sintering condition.
