Abstract: A filter for the purification of gases in respect of mercury comprises a casing (2) with an inlet opening (7), an outlet opening (8) for the gases which shall be purified in respect of mercury, in the casing a filter body (10) consisting of a very large number of layers of thin foil (17, 18) which on each side is covered with a thin gold layer, between said layers of gold plated foil, channels (19) for gas which shall be purified in respect of mercury and for gas intended to be fed through the filter during the regeneration of the filter. Means (20) are provided for heating said foil and said gold layers deposited on the foil to above 200 DEG C in connection with the regeneration of the filter. Said foil, which defines the substrate for the gold layers, consists of, or exhibits on each side thereof, a surface layer consisting of a material which can not be alloyed with gold through diffusion of gold from the gold layers during heating to or at the regeneration temperature.

Abstract: The present invention relates to a method to manufacture a composite ceramic material having a high strength combined with bioactive properties, when the material is used as a dental or orthopedic implant, which includes preparing a powder mixture, mainly comprising partly a first powder, which in its used chemical state will constitute a bioinert matrix in the finished material, and partly a second powder, mainly comprising a calcium phosphate-based material. The invention is characterized in that said first powder comprises at least one of the oxides belonging to the group consisting of titanium dioxide (TiO2), zirconium oxide (ZrO2) and aluminum oxide (Al2O3), in that said second powder mainly comprises at least one of the compounds hydroxylapatite and tricalcium phosphate, in that a raw compact is made of said powder mixture and in that said raw compact is densified through an isostatic pressing in a hot condition (HIP) at a pressure higher than 50 MPa, a composite material being obtained, in which said matrix comprises one or several metal oxides of said first powder, in which matrix said compound hydroxylapatite and/or tricalcium phosphate is evenly dispersed. The invention also relates to a composite ceramic material as well as a body, completely or partially made of this material.
