Abstract
The present invention relates to a heat-resistant expansive member suitably used as a holding member for holding a ceramic monolithic catalyst in a motor vehicle or the like. The heat-resistant expansive member of the present invention is made at the blending ratio of 1 to 5 wt % of sepiolite, 30 to 60 wt % of treated vermiculite, 20 to 40 wt % of ceramic fibers and 5 to 20 wt % of an organic binder, or at the blending ratio of 21 to 30 wt % of sepiolite, 30 to 40 wt % of treated vermiculite, 20 to 40 wt % of ceramic fibers and 5 to 20 wt % of an organic binder. Regardless of the low- or high-temperature zone, the heat-resistant expansive member of the present invention presents a great holding force to the monolithic catalyst or the like. The heat-resistant expansive member is improved in cushioning properties and gas-attack resisting properties particularly in the high-temperature zone.
