Raw data for "Mechanochemical Activation of Rice Husk Ash for SiC Synthesis: Effects of Ball Diameter on Silica Activation and SiC Formation"

Methods

The data were generated through the following characterization techniques:X-ray Diffraction (XRD): Crystalline phase identification and structural evaluation of RHA-derived materials across different synthetic conditions and heat-treatment temperatures.Fourier Transform Infrared Spectroscopy (FTIR): Chemical bond and functional group analysis of synthesized samples.Laser Diffraction Particle Size Analysis: Particle size distribution measurement of heat-treated and HF-etched RHA-derived samples.File Content and Naming RulesThe uploaded files are provided in Excel (.xlsx) formats.

They are systematically named after the characterization methods and organized by the corresponding figure numbers referenced in the associated manuscript:XRD.xlsx: Contains XRD patterns for initial/as-synthesized samples (Sheet Figure 1a,b) and high-temperature heat-treated samples (Sheet Figure 3 & S4).FTIR.xlsx: Contains FTIR spectral data (wavenumber vs. intensity) for synthesized samples (Sheet Figure 1c,d).Laser diffraction.xlsx: Contains particle size distribution data (particle size vs. frequency) for heat-treated and HF-etched samples (Sheet Figure 5).Data Column Name Explanations & Units2θ / degree: Diffraction angle in degrees (°) for XRD patterns.Intensity / a.u.: Signal intensity expressed in arbitrary units for XRD and FTIR spectra.wavenumber / cm-1: Infrared radiation frequency in reciprocal centimeters ($\text{cm}^{-1}$) for FTIR spectroscopy.Particle size / μm: Equivalent sphere particle diameter in micrometers ($\mu\text{m}$) for laser diffraction measurements.Frequency / %: Relative volume/number percentage of particles at a given particle size.Value and Potential Reuse of the DataThis dataset offers a comprehensive, highly valuable experimental reference for biomass-derived silica/carbon materials and ceramic matrix precursors.

It enables researchers in materials science, environmental technology, and sustainable chemistry to:Re-analyze phase transformations, local bonding environments, and morphological evolution during high-temperature treatments of RHA-derived composites.Utilize precise structural and particle distribution parameters for comparative benchmarking against other agricultural-waste-derived ceramic materials.Serve as reference experimental inputs for data-driven modeling or thermodynamic calculations of bio-based silica composite synthesis.
