ABSTRACT:
A method of creating a water resistant, silicate-based ceramic composite article is disclosed. The method comprises depositing the silicate-based ceramic composite article in a container; immersing the silicate-based ceramic composite article in a solution comprising water and a soluble chemical that reacts with high alkali ions present in the silicate-based ceramic composite article and reduces the pH of the silicate-based ceramic composite article; soaking the silicate-based ceramic composite article in the solution for a period of time; removing the silicate-based ceramic composite article from the solution; and drying the silicate-based ceramic composite article.
