    Abstract: The present invention relates to compositions comprising from 1 to 7 wt.-% organic binder, from 0 to 50 wt.-% water and an inorganic particulate material selected from talc, wollastonite or a mixture thereof. The compositions may be compressed compositions such as compressed granulated compositions, such as a brick, a briquette, a pellet, a pressing, a mould, a preform, a spray-dried powder, a tablet, an aggregate, a rod, a granulate, or an agglomerate, or any mixture thereof. The invention further relates to methods of making these compositions and their use.

    Abstract: The present disclosure relates to surface-functionalized carbonaceous particles, optionally in agglomerated form, methods for making such surface-functionalized carbonaceous particles and their use, for example as conductive additives in battery electrodes. The surface-functionalized carbonaceous particles are for example obtainable by milling a non-graphitic carbon material, followed by subsequent functionalization through controlled oxidation. The surface-functionalized carbonaceous particles can be used as additive in battery electrodes. The disclosure also pertains to dispersions of such carbonaceous materials in a liquid medium and their use as, among others, conductive coatings. Polymer compounds filled with the surface-functionalized carbonaceous particles are also disclosed.

    Abstract: The present invention relates to an agglomerate abrasive grain made up of a plurality of individual abrasive grains which are bonded into an inorganic or organic binder matrix, wherein, based on the total weight of the agglomerate abrasive grain, at least 8% by weight of the abrasive grains which are bonded into the matrix are fused alumina-based polycrystalline alumina abrasive grains with a percentage of more than 97% by weight of alpha-alumina, and wherein the polycrystalline alumina abrasive grains, in turn, are made up of a plurality of Al2O3 primary crystals with a crystal size of between 20 μm and 100 μm. The agglomerate abrasive grain has a closed macroporosity with a pore volume of between 5% by volume and 30% by volume, wherein the average pore diameter of the closed macropores is between 10 μm and 100 μm and their maximum pore diameter is in the range of approx. 120 μm.
