Systems and methods for forming a permanent plug in a subterranean formation include providing a solution of colloidal silica and pumping the colloidal silica into a bore of a subterranean well so that the colloidal silica penetrates pores of the subterranean formation. The colloidal silica within the pores of the subterranean formation is dehydrated to form a glass-like material within the pores of the subterranean formation.

In a method of making a gaseous emissions treatment component, a green ceramic mix is extruded through a die to form an extrusion having cells extending along the extrusion, the cells being bounded by walls dividing adjacent cells from one another. In concert with the extruding, metal is fed through the die with the extruded mix. A length of the extrusion and associated metal is then cut off and fired to form the component.

In a process for manufacturing a catalytic converter component, a ceramic unit is used that has been prepared by extruding green ceramic product through a die to form an extrusion having a honeycomb substrate structure in which tubular passages extend along the extrusion, the passages bounded by walls dividing adjacent passages from one another. The unit is obtained by cutting off a length of the extrusion and curing and firing it. The process further comprises, following the firing, injecting a mixture of a mastic component and a particulate metal component from an end of the ceramic unit into selected ones of the cells so as to block the selected cells over at least a part of the lengths thereof while maintaining all of the walls of the ceramic unit, and curing the injected material to render the injected material solid.

A gaseous emissions treatment component is made by extruding a green ceramic mix through a die to form an extrusion having a honeycomb substrate with elongate cells extending its length and with the cells bounded by walls dividing adjacent cells from one another. Molten metal for use in induction heating of the component is placed in selected cells and is solidified by cooling.

In a process for manufacturing a catalytic converter component, a ceramic unit is used that has been prepared by extruding green ceramic product through a die to form an extrusion having a honeycomb substrate structure in which tubular passages extend along the extrusion, the passages bounded by walls dividing adjacent passages from one another. The unit is obtained by cutting off a length of the extrusion and curing and firing it. The process further comprises flowing insulation material from one end of the unit into selected ones of the elongate passages, the insulating material then being cured. The passages are selected so that the cured insulation material forms an internal thermal insulating barrier between a core zone and a radially outer zone of the unit. Passages in the inner and outer zones are free of insulation material and the honeycomb structure walls include walls crossing the insulating barrier.
