The present invention relates to advanced multi-functional asbestos-free thermal insulating materials utilizing appropriate matrixes comprising nano thermal insulating precursor powder predominantly comprising calcium silicate and calcium magnesium silicate prepared from marble waste powder, rice husk and calcium hexametaphosphate; crushed silica fiberglass and a supporting matrix.

In a process for manufacturing a component for an emissions treatment unit, green ceramic product is extruded through a die to form an extrusion having a honeycomb substrate structure with an array of parallel, linear tubular cells extending along its length, the cells bounded by walls dividing adjacent cells from one another. A ceramic unit is obtained by cutting off, curing and firing a length of the extrusion a length of the extrusion. Following the firing, a mixture of a flowable, uncured curable material and a particulate metal component is injected 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 their lengths while maintaining all of the walls of the ceramic unit. The injected mixture is then cured to render it solid.
