Effect of the Agglomerated State on the Photoalytic
The photoalytic production of H2 in aqueous TiO2 colloid (with methanol as an electron donor) was greatly accelerated by the in situ agglomeration of the colloid although such an agglomeration should reduce the photoalytic activity in most other cases because of the reduction of the surface area. The in situ agglomeration occurred after an induction period of 3 h and was ascribed to the

The Effect of Presence of SiO2, Al2O3 and SpringerLink
May 24, 2016 · Abstract. A detailed investigation is made to study the effect of the presence of gangue materials like SiO 2, Al 2 O 3 and P 2 O 5 on the reducibility of iron ores in the blast furnace and sponge iron/DRI plants. The shatter index and abrasion index are found to improve marginally with increased content of the gangue materials, though the improvement is not significant.
use of unconventional raw materials in the reductionfusion process are agglomerates based on iron ore/coal. Innovative studies  have reported that the use of other materials different than the hematite, mainly goethite, have a high degree of reduction and metallization under specific conditions [3,4].
