Chapter 21, Problem 21.117SP

Interpretation Introduction

Interpretation:

To write the chemical formula of the ceramic obtained when the gel is dried and sintered and describe the reactions that occur when a Y(OH)₃ sol becomes a gel.

Concept introduction:

Sol-gel method is a method for production of solid materials from small molecules. Sol-gel method is useful for production of metal oxides i.e. oxides of silicon or titanium.

Ceramics are inorganic, non-metallic, non-molecular solids, including both crystalline and amorphous materials. Ceramics has a higher melting points, they are stiffer, harder, and more resistant to wear and corrosion than are metals

To write:

The chemical formula of the ceramic obtained when the gel is dried and sintered and also describe the reactions that occur when a Y(OH)₃ sol becomes a gel.
