Claim:
1. A composite nonwoven fibrous web comprising: an embedded phase of particulates forming a substantially continuous three-dimensional network of particulates, wherein all of the particulates in the embedded phase collectively make-up a population of particulates including all particulates in the nonwoven fibrous web, wherein each individual particulate of the population of particulates of the embedded phase is in surface to surface contact with at least one other particulate of the population of particulates of the embedded phase, further wherein each individual particulate of the population of particulates of the embedded phase is inorganic; and a matrix phase comprising a population of fibers forming a three-dimensional network around the embedded phase, wherein the composite nonwoven fibrous web has a thickness and exhibits a Solidity of less than 10%.
