摘要： A method of agglomerating bulk ceramic fibers includes mixing the bulk ceramic fibers with water to form wet fibers; mixing the wet fibers with a binder including an organic binder and/or an inorganic binder to form agglomerates; and drying the agglomerates. The agglomerates may be mixed with additional binders and fillers to form an insulating mix that may be used to insulate a furnace or other heat source. A foaming nozzle may be used for the application of agglomerates. A foaming agent and water are air atomized within the foaming nozzle and the resulting foam is mixed into pneumatically conveyed agglomerates, which result results in a lightweight refractory material layer on a target substrate.

摘要： There is disclosed a spray gun for spray deposition of 2D material onto substrate surfaces so as to allow for subsequent laser patterning or etching of said material into a metamaterial. The gun comprises: a housing 1 capable of accepting a propulsion device for propulsion of the material, wherein said housing 1 accommodates a reservoir for loading material to be deposited by spraying; and a nozzle 4 for directing the material to be sprayed by the gun. The nozzle 4 includes converging and diverging inner bore sections so as to enable propulsion of material at a supersonic speed.

摘要： A powder spraying system comprises a source of dry powder (4), a spray nozzle (25), and a supply conduit (16) connecting the source of dry powder with the spray nozzle. The spray nozzle comprises a nozzle body (50) having a nozzle outlet (51), a first conduit (52) for dry powder, and a second conduit (53) for gas. The first conduit extends between a powder inlet (54) in communication with the supply conduit and a powder outlet (55). The second conduit extends between a gas inlet (56) and a gas outlet (57), the gas outlet being located in proximity to the powder outlet such that a gas flowing through the second conduit and out of the gas outlet produces a suction force at the powder outlet to promote flow of a dry powder through the first conduit and out of the powder outlet and the nozzle outlet. The powder outlet and the gas outlet are orientated to promote mixing of the gas with the dry powder. The first conduit (52) is a straight conduit between the powder inlet (54) and the powder outlet (55).
