Nucleation and growth of hexagonal CaAl 2 Si 2 O 8 crystals in CaO–Al 2 O 3 –SiO 2 glass
Source abstract
Abstract
Abstract Hexagonal CaAl 2 Si 2 O 8 was precipitated inside of 25CaO–20Al 2 O 3 –55SiO 2 (wt%) glass by heat treatment at 1050 °C with MoO 3 and carbon as nucleating agents. Transmission electron microscopy revealed that metallic molybdenum particles with sizes of ∼200 nm precipitated in the glass and served as heterogeneous nucleation sites for plane-like hexagonal CaAl 2 Si 2 O 8 crystals with widths greater than 10 μm and thicknesses of ∼1 μm. The thickness direction was the c -axis of hexagonal CaAl 2 Si 2 O 8 .
