5 results about "Metal particle" patented technology

Method of producing a gas-tight solid electrolyte layer for a high-temperature fuel cell, wherein a layer is produced from a metal oxide material and metal particles are incorporated in the layer during production of the layer, the metal particles being oxidizable, and wherein the metal particles are subsequently oxidized.

The invention provides a fabrication method and an application method of alumina cement. The fabrication method comprises the following steps: evenly mixing aluminium powder, silicon powder and chrome powder; burning the mixed powder into metal particles; screening the obtained metal particles into a first metal particle group, a second metal particle group, a third metal particle group and a fourth metal particle group by using a screening machine; respectively roasting the first metal particle group, the second metal particle group, the third metal particle group and the fourth metal particle group; cooling the first metal particle group, the second metal particle group, the third metal particle group and the fourth metal particle group to room temperature; evenly mixing the first metal particle group, the second metal particle group, the third metal particle group and the fourth metal particle group according to the mass ratio of 3:3:2:2; evenly stirring a binder with the particles according to the mass ratio of 1:1. The alumina cement is directly sized and applied on the surface of an article to use. The alumina cement provided by the invention is wider in application range, convenient to use, good in wear-resisting property and low in fabrication cost.
