A series of sintered glass-ceramics belonging to the system diopside–albite, forming by surface crystallization 30, 50 and 65% diopside, was investigated. In order to study the effect of bulk crystallization on the sintering a 0.7% of Cr2O3 as nucleation agent was added in one of the compositions. The crystallization was evaluated by DTA and density measurements and the degree of densification ...

Diopside (DS) is a monoclinic pyroxene mineral with composition MgCaSi2O6. Lately,diopside (DS) has beenintroduced as a bioceramics due to its best bioactivity and biocompatibility. It has a good strength andtoughness than those of hydroxyapatite (HT). In this project, bioactivity of diopside (DS) powder wereevaluated and investigated. For synthesized of diopside (DS) powder, ...

Occurrences of diopsidites, rocks made predominantly gem-like diopside whose composition precludes a purely igneous origin, allow tracking the pathway high-temperature fluids and fluid-saturated melts in oceanic lithosphere vicinity mantle-crust transition zone (the Moho) adjacent mantle an setting. We have experimentally explored origin diopsidites by reacting serpentinite with synthetic haplo...

The prograde metamorphism of eclogites is typically obscured by chemical equilibration at peak conditions and by partial requilibration during retrograde metamorphism. Eclogites from the Eastern Blue Ridge of North Carolina retain evidence of their prograde path in the form of inclusions preserved in garnet. These eclogites, from the vicinity of Bakersville, North Carolina, USA are primarily co...

Weathering of primary silicate minerals under acidic conditions occurs in contexts as varied acid mine drainage, volcanic environments, soils, stone monuments subjected to rain or Geological Carbon Storage (GCS). Considering the abundance pyroxenes on Earth crust, knowledge their weathering kinetics and mechanisms may help optimize carbonate yield GCS. Here we report experimental results from r...
