A composite gel or aerogel is formed by commingling a particulate guest such as a colloidal or dispersed i.e., non-colloidal solid or a powder with a sol which is either about to gel or in which gelation has just started. After addition of the particulate, the mixture is then permitted to gel into a solid, gelled composite with open pores. This solid, gelled composite is then dried in a manner that prevents the collapse of open pores within the solid, gelled composite in which the gel acts as a nanoglue that holds the particles together.
