ABSTRACT:
A process for forming a porous refractory mass on a surface is characterized in that an oxidizing gas is projected against that surface together with a powder mixture which comprises: refractory particles; particles of fuel which reacts exothermically with the oxidizing gas to form refractory oxide and release sufficient heat to melt at least the surfaces of the refractory particles so that they bond together to form the refractory mass; and particles of material whose composition and/or size is selected so that the incorporation of such material in the projected mixture results in the formation of porosity within the refractory mass formed. The porosity-inducing material may be such as to burn to evolve gaseous combustion products, it may decompose to gaseous decomposition products, or it may itself be porous or hollow.
