Amorphous layers are made by decomposing one or several gaseous compounds which include an element or elements to be deposited. These are group 3 and 5 or group 4 elements but amorphous layers of other metals can also be made. The compound is added in a small concentration to a hot gas, preferably hydrogen, helium or argon and a diffusor accelerates the mixture while molecular clusters of the element or elements are formed and impinge upon a target for depositing thereon.

Making an amorphous layer

Subject of the invention is a diesel-soot filter with catalytically-active coating for reducing the ignition temperature of the diesel-soot deposited on a filter, the active substance of the coating being a metal-doped zeolite.
