The use of colloids in the production of ceramics is primarily for:
Reducing the mechanical strength of ceramics
Increasing the porosity of ceramics
Enhancing the homogeneity and sintering behaviour of ceramics
Eliminating the need for firing processes
Colloids are used in the production of ceramics to improve the homogeneity of ceramic slurries and facilitate the sintering process, resulting in denser and more uniform ceramic products.
Hence option 3 is correct.
