An increasing number of studies are being presented demonstrating that volcanic glasses
can be heterogeneous at the nanoscale. These nano-heterogeneities can develop both …

A viscosity jump of one to two orders of magnitude in the lower mantle of Earth at 800–1,200-
km depth is inferred from geoid inversions and slab-subducting speeds. This jump is known …

A spodumene glass (LiAlSi 2 O 6), doped with 4 mol% TiO 2 as a nucleating agent, was
synthesized by containerless melting. Its accurate viscosity characterization by …

SiO 2-TiO 2 glasses produced by aerodynamic levitation coupled to laser heating or by sol-
gel spray-drying were compared to highlight their structural differences. Glass formation was …

Stuffed aluminosilicate quartz solid solutions (Qss) represent the main functional component
of state-of-the-art zero-thermal-expansion glass-ceramics. For the first time, we present the …

In recent years, the vitrified bond diamond grinding wheel has been applied widely in
automotive, aerospace and machine tools of manufacturing industries. However, the main …

An understanding of the crystallization sequence (the formation order of crystalline phases)
of glasses is crucial for the processing and composition design of novel glass-ceramics. A …

Le comportement structural des cations dans les verres d'oxydes multicomposants ne peut
pas être décrit dans un modèle de réseau aléatoire, en raison de la présence d'agrégats de …

SiO2–TiO2 amorphous nanobeads with a TiO2 content up to 50 mol% were synthesized by
sol–gel spray drying. Their crystallization during heat treatments was then characterized by …

The impact of TiO 2 additions on the quenchability of melts derived from the stoichiometry of
spodumene (LiAlSi 2 O 6), eucryptite (LiAlSiO 4) and nepheline (NaAlSiO 4) was …
