Ball milling technology is the classical technology to isolate representative lignin in the cell wall of biomass for further investigation. In this work, different ball milling times were carried out on hardwood (poplar sawdust), softwood (larch sawdust), and gramineous material (bamboo residues) to understand the optimum condition to isolate the representative milled wood lignin (MWL) in ...

Zirconium silicate: We use milled zirconium silicate having average size of grains 25 microns (grains of original zircon sand are too big for a rapid dissolving of material in the liquid frit). Zircon starts to melt at 1380C forming a liquid phase and zirconium oxide, but its solubility in the liquid phase is poor and dissolving time quite long.

Main resource of zirconia is the mineral zircon which occurs in beach sand and placer deposits. Alkali fusion and thermal plasma dissociation are the frequently adopted procedures to convert zircon to zirconia. Synthesis of different zirconia phases (monoclinic, cubic, and tetragonal) can be accomplished by the precise control of different operating parameters and stoichiometry of the reagents.
