    • The invention relates to a filter for removing particles from a gas stream, in particular soot particles from an exhaust gas stream of an internal combustion engine. Said filter comprises a filter body consisting of a ceramic filter substrate, the latter being coated with a porous protective layer of (46, 48) coating material. The invention is characterised in that the coating material contains an admixture of between 1 and 20 % by weight of at least one compound of an element of the 2nd main group of the periodic table, preferably an oxide of an element of the 2nd main group, and that cracks (44) in the ceramic filter substrate are partially filled with the coating material. The invention also relates to a method for producing a filter, according to which the coating material for the porous protective layer (46, 48) is applied to the sintered ceramic filter substrate, at least one compound of an element of the 2nd main group is added, other substances contained in the protective layer (46, 48) are optionally added and the porous protective layer (46, 48) is fixed.
    • 本发明涉及一种用于从气流中去除颗粒的过滤器,特别是来自内燃机废气流的烟灰颗粒。 所述过滤器包括由陶瓷过滤器基材组成的过滤器主体,后者涂覆有(46,48)涂层材料的多孔保护层。 本发明的特征在于,涂料含有1至20重量%的至少一种元素周期表第2主族元素的化合物,优选第2主族元素的氧化物的混合物, 并且陶瓷过滤器基板中的裂纹(44)部分地被涂覆材料填充。 本发明还涉及一种过滤器的制造方法,根据该方法,将多孔保护层(46,48)的涂料施加到烧结陶瓷过滤器基材上,第二主要组分的至少一种化合物为 添加了保护层(46,48)中所含的其他物质,并且多孔保护层(46,48)被固定。
