An investigation of the chemical composition and acid corrosion of pedra sabão (soapstone)
In this paper the results of a basic study of the chemical composition and structure of soapstone are reported. An investigation of the effects of aqueous sulfuric acid solutions on the physical integrity of the stone was also performed. The studied soapstone samples had a lamellar nanostructure as...
