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.
