Abstract
A supporting member of the papermaking screen in paper machines is disclosed, which is made with a sintered body consisting essentially of silicon nitride, having a porosity of less than about 0.8% whereby the abrasion loss rate of the papermaking screen is able to be remarkably reduced as compared with the conventional supporting members made of alumina ceramic, as a result of which the useful life of the papermaking screen can be lengthened greatly.
