Interpretation: The steps used to form a ceramic material from scandium and ethanol using sol-gel process has to be explained.
Concept Introduction:
Ceramics are polymeric inorganic solid compounds consists of non-metal, metalloid or metal atoms held together by covalent and ionic bonds. When an inorganic substance is melted and solidified, it results in ceramics.
Ceramics are hard and have high melting points. They are heat insulators.
Ceramics have crystalline or amorphous structure.
Example: Glass
A process called sintering is to prepare ceramics. The resulting product was irregular in shape with cracks, spaces and imperfections. Hence, sol-gel method was employed to prepare ceramics of uniform size without much of cracks and gaps.
