An attempt to obtain Bi_{4}Ti_{3}O_{12}-PVC textured ceramics-polymer composites
, 2013 Bi_{4}Ti_{3}O_{12}-PVC composites were fabricated. Ceramics powders of bismuth titanate were prepared by the sol-gel method using bismuth nitrate pentahydrate Bi(NO_{3})_{3} \cdot 5H_{2}O and tetrabutyl titanate Ti(CH_{3}(CH_{2})_{3}O)_{4} as precursors.

, 2017 Fine limestone has been added to Portland cement for decades. This is normally achieved by “intergrinding” it with Portland cement clinker in the cement mill. Under normal operating conditions this will result in a surface area of the limestone fraction of between 800 and 1100 m2/kg (depending on the grindability of the limestone) for a surface area of

Direct Powder Forging—A New Approach for near Net Shape Processing of Titanium Powders
Powders, 2023 This study investigates direct powder forging (DPF) as a new approach for near-net-shape processing of titanium alloys using a coarse particle size distribution (PSD) between 90 and 250 μm.
