Functionality Based Design of Sustainable Bio-Composite

The composites were designed by a two-step process: in situ polymerization in NR latex followed by compounding in a two-roll mill. It was noted that the natural rubber/polypyrrole composite's DC conductivity was only improved at very high polypyrrole load and a maximum conductivity of 8.3 × 10 −4 S/cm was reached at loading time of 100 phr .

Mullite-Based Ceramics from Mining Waste: A Review

For the complete transformation of kaolinite into mullite by the sintering process, very high temperatures are required (1600-1700 °C) due to the diffusion coefficient of mullite in the grain border being very low. To reduce the mullitization temperature, it is convenient to use systems to mix raw materials at the atomic level. Fused-mullite.
