Abstract (en)
[origin: WO9825685A1] The invention relates to a filter element for fluids, the filter element being resistant to high temperatures, in particular 800...1600 DEG C, and comprising a support layer and a coating formed thereon, the pore size of the support layer being greater than the pore size of the coating. The invention is characterized in that the support layer is made up of inorganic structural particles bonded together by means of a reaction product produced in a reaction-sintering process between the said structural particles and a binder formed by an inorganic starting component, and that at minimum 60 % by weight of the structural particles used are structural particles having a diameter of 87...1000 mu m as determined by the screening method. The invention also relates to a novel support layer and to methods for fabricating the support layer and the filter element.
