2. Which approach can be employed to produce a high degree of homogeneity in the creation of ZnFe2O4 spinel? a) Distillation method b) Vaporization method c) Coprecipitation method d) Crystallization method
Answer: c Explanation: The reactants are mixed together manually or mechanically in a conventional solid state reaction, and the ensuing reaction rate is largely determined by the degree of homogeneity accomplished during mixing and the intimacy of contact between the grains. With the Coprecipitation method, a high degree of homogeneity can be achieved while maintaining a tiny particle size, speeding up the reaction pace.
