CY3202 Solid State Chemistry Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
• To understand and apply the basics of principles of solid state chemistry.
• To identify and apply the concepts involved in the syntheses, structure and physical properties of crystalline inorganic solids.
• To apply various techniques for the preparation of different types of solids.
• To understand the principles of solid characterization techniques.
UNIT I CRYSTAL STRUCTURE
Solids-Types-Crystalline, Amorphous and poly crystalline; Properties: Isotropy and anisotropyinterfacial angles-symmetry in crystal systems-elements of symmetry – space lattice and unit cell, Bravias lattice-seven crystal systems. Bond types: molecular, covalent, metallic and ionic. BornHeber Cycle, Lattice energy, Imperfections in crystal-stoichiometric defects-Schottky, Frenkel, Nonstoichiometric defects-Colour Centre, F-Centre
UNIT II ELECTRICAL PROPERTIES
Band theory of solids -metals and their properties; semiconductors – extrinsic and intrinsic, insulators – dielectric, ferroelectric, pyroelectric and piezoelectric properties, multiferroics. Superconductivity: Basics, discovery and high Tc materials.
UNIT III MAGNETIC PROPERTIES
Dia, para, ferro, ferri, and antiferro magnetic types; soft and hard magnetic materials; select magnetic materials such as spinels, garnets and perovskites, hexaferrites and lanthanide-transition metal compounds; magneto resistance
UNIT IV SYNTHETIC METHODS

Sol-Gel, Co-precipitation, microwave assisted synthesis, combustion synthesis, High pressure methods for preparing single crystals-Czochralski, molecular beam epitaxy-Flame and plasma fusion methods, intercalated compounds.
UNIT V SOLID CHARACTERIZATION TECHNIQUES
Powder x-ray diffraction, indexing the powder XRD patterns, Systematic absences, Structure factor, determination of lattice type, unit cell parameter and density for fcc, bcc and hcp metals, Thermal analysis: TGA, DTA, DSC
COURSE OUTCOME:
At the end of the course, the learners should be able to:
