The use of cellulose template can help in synthesizing high-purity barium hexaferrite, but adding too much can decrease magnetic properties. The addition of cellulose template leads to a reduction in crystallite size.
Nanocrystalline cellulose templated barium hexaferrite has been prepared by sol-gel auto combustion and calcination method. Nanocrystalline cellulose template of 0, 0.5%, 1.0%, and 1.5% (w/v) were used to synthesize barium hexaferrite. The XRD pattern and TEM observation reveal the crystalline phase formation of hexagonal barium ferrite. Cellulose template changes the microstructure and properties of barium hexaferrite. Adding cellulose template of 0.5% (w/v) produce well-defined hexagonal platelet barium ferrite without impurity while adding more template result in barium hexaferrite containing hematite and excess cellulose template causing the decrease in magnetic properties. The crystallite size reduces with the addition of the cellulose template. The saturation magnetization and magnetocrystalline anisotropy are estimated using the Law of Approach to Saturation magnetization. The maximum values of saturation magnetization and magnetocrystalline anisotropy are 57.43 +/- 0.25 emu g(-1) and (4.64 +/- 0.1) x 10(5) erg cm(-3).
