Nanoscale powders of hydrated Ca₂P₂O₇, CaCO₃, and a product of mixed-anionic composition containing P₂O₇⁴⁻ and CO₃²⁻ anions were synthesized from aqueous solutions of Ca(CH₃COO)₂, pyrophosphoric acid (H₄P₂O₇), and/or (NH₄)₂CO₃. Pyrophosph...

Apatite is widely used in medicine as a biomaterial for bone tissue restoration. Properties of apatite depend on its composition, including the Ca/P ratio. This paper shows what range of Ca/P ratio can be attained in apatite by the mechanochemical me...

This work aimed to study the oxidation resistance of γ-TiAl based alloy, doped with small concentrations of carbon, silicon, and yttrium oxide in air at 800 and 1100 °C for 30 h. The TNM-B1 alloy samples were produced via high-energy ball m...

In this paper, partial transient liquid phase (PTLP) diffusion bonding between Si₃N₄ ceramics and Ht250 cast iron was carried out by using an Ti/Cu/Kovar/Cu/Ti interlayer. The effects of the heating temperature and holding time on the microstructure,...

Powders of alkyl phosphoric acids and calcium alkyl phosphates with various alkyl chains (butyl, octyl, and dodecyl) have been synthesized. The resulting powders were characterized by X-ray phase analysis, electron microscopy, and thermal analysis. I...

Alumina and zirconia thin films modified with colored nano-Fe_xO_y pigments were sintered by the flash-lamp-annealing method. We selected a nano α-Al₂O₃ and micron α-Al₂O₃ bimodal mixture as the base precursor material, and we doped it with...
