Preparation of ceramic nanospheres by CO2 laser vaporization (LAVA)

Risk and life cycle assessment of nanoparticles for medical applications prepared using safe- and benign-by-design gas-phase syntheses

“…The (Co)LAVA methods were previously described in detail elsewhere. 16 Briefly, these methods use a CO 2 laser beam which is focused onto the surface of coarse ceramic starting powders. The LAVA process starts from a single ceramic raw powder, while the starting materials of the CoLAVA process are defined, homogeneous mixtures of ceramic raw powders.…”

“…15 In this article, an early stage comparative LCA and nanomaterial specific RA study of oxidic nanoparticles, produced using laser vaporisation (LAVA) of a single metal oxide powder and by co-vaporisation (CoLAVA) of homogeneous mixtures of metal oxide powders, is presented. These laser-induced production processes for oxidic nanoparticles 16 were assessed for three reasons. First of all, the (Co)LAVA technologies are well suited for the continuous and reproducible production of high quality nanopowders with merely softly agglomerated, spherical nanoparticles of defined crystal phase(s) and narrow diameter distribution.…”

Design of a New Zirconia–Alumina–Ta Micro‐Nanocomposite with Unique Mechanical Properties

“…Based on our previous research, the CO 2 laser covaporization (CoLAVA) method was chosen for the preparation of a zirconia–alumina hybrid nanopowder to avoid an inhomogeneous distribution of both phases . Nevertheless, the resulting ceramic materials remain brittle.…”

Europium(III)‐Doped MgAl2O4 Spinel Nanophosphor Prepared by CO2 Laser Co‐Vaporization

“…However, as a negative side effect the primary NPs fused into hard aggregates. In contrast, MgAl 2 O 4 spinel with its very stable cubic structure should be suitable to form crystalline NPs even at the high quenching rates of the CoLAVA process.…”
