The growth of sapphire single crystals [PDF]

open access: yesJournal of the Serbian Chemical Society, 2001
Sapphire (Al2O3) single crystals were grown by the Czochralski technique both in air and argon atmospheres. The conditions for growing sapphire single crystals were calculated by using a combination of Reynolds and Grashof numbers.

Quantitative Description of Duplex Stainless Steels Microstructure Using Selective Etching

open access: yesMetals, 2021
The properties of duplex stainless steels (DSSs) depend on the ferrite–austenite ratio, on the content of secondary phases and on the contamination with non-metallic inclusions. To assess the quality of DSSs, it is necessary to use an integrated approach

Manipulating etch selectivities in XeF2 vapour etching [PDF]

open access: yesJournal of Microelectromechanical Systems, 2021
The vapour etching of silicon sacrificial layers is often a critical process in the fabrication of micro/nanosystems. This method has a number of attractive features, in particular, high etch rates of sacrificial silicon layers and good selectivities associated with photoresist, SiO₂, stoichiometric Si₃N₄ and a number of regularly used metal films ...
