Interpretation: Would the metal alkoxide in sol-gel process be acidic or basic has to be justified
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 partly crystalline or cystalline or amorphous structure.
Ceramics was prepared by a process called sintering. 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.
