polymer composites that possess high-performance. This study was conducted to explore the specifc properties of a novel
micro-sized cellulosic fllers obtained from Nelumbo nucifera leaves and thereby to establish its feasibility as composite reinforcement. The physico-chemical, surface and thermal behaviours are investigated for cellulosic micro fllers that extracted
through thermo-chemical method. The density of the extracted fllers was analysed to realize its mode of applicability.
Whereas chemical characterization studies were indispensable to explore the chemical nature of the material. Of which, X-ray
difraction analysis proved that Nelumbo nucifera leaves has good crystallinity index (75.9%) and crystalline size (8.2 nm).
The Fourier Transform Infrared Spectrometer analysis showed that the material possesses high cellulosic contents rather very
less non-cellulosic residues. Scanning electron microscope images disclosed the roughness pattern of the fller surface and
subsequently the average particle size of the micro fllers is identifed as 23.253±6.55μm through ImageJ tool. At the same
time, atomic force microscopy images revealed that micro cellulose extracted has desired average roughness (28.296 μm).
Though, the suitable surface features of Nelumbo nucifera leaves are found to be virtuous for providing interfacial bonding
with other matrices during composite formulation. Along with that, good thermal stability (215°C) ofers its processing and
application even at relatively higher temperatures. Since, the present study has accomplished that Nelumbo nucifera leaves is
a promising alternative source of micro cellulose for traditionally used sources like wood, hemp, and cotton, for the extraction
of micro cellulose, which could be further used as a promising alternative to synthetic reinforcements.

This comprehensive work provides a general overview of the approach, along with a discussion of its guiding principles and applications in the synthesis of new materials. Direct interaction between solid reactants at high temperatures, usually in a controlled environment or under pressure, is the foundation of the SSR process. Diffusion, crystalline development, and internal solid-phase chemical processes are the foundations of this approach. Some common steps in a solid state reaction, like reactant mixing, heating, and cooling are described in the overview. The importance of temperature profiles, stoichiometry, and precursor choice in determining the calibre of the final product is emphasized. In this review, various materials that can be produced using the solid state reaction approach are examined. This includes ceramic superconductors, phosphors, batteries, catalysts and battery components. Characterizing methods for measuring the phase purity and inspecting the microstructure of solid state reaction products, such as X-ray diffraction (XRD), scanning electron microscopy (SEM) and other spectroscopy techniques are emphasized. The review talks about how the solid state reaction process affects the environment and emphasizes how solvent-free it may be. This requires the development of novel precursor materials, the use of state-of-the-art characterization techniques, and the use of computer modeling in order to produce new materials with specified properties.
