Abstract
The porosity and surface roughness of ceramic substrates are improved by coating the surface with silicon compounds, drying the coated substrate, and then subjecting the substrate to elevated temperature so as to convert the silicon compounds to silicon oxides. Coated substrates obtained by the above process as well as specific preferred organosilane compositions are provided.
