Zirconia toughened alumina (ZTA) is one of the widely discussed advanced ceramic in
recent times. ZTA boasts excellent mechanically properties such as high hardness, high …

The crystal structure of hibonite with an ideal formula CaAl 12 O 19 is hexagonal P6 3/mmc,
isostructural with magnetoplumbite. Natural and synthetic hibonites have been widely …

Blue pigments based on Ni 2+ and La 3+-doped hibonite, Ca 1-x La x Al 12-x Ni x O 19,
show high total solar reflectance and act as cool pigments to prevent surface overheating …

Colored hibonite-type oxides with a general formula CaAl 12-x M x O 19 were prepared by
solid state reactions through M-site substitution of aluminum with various di-, tri-and …

Cement-bonded alumina–magnesia refractory castables present excellent properties
because of the in situ spinel and calcium hexaluminate formation. However, controlling the …

The current paper gives an overview of the development of Raman spectrometry in
gemmological laboratories. While before 1990s, no commercial gemmological laboratory …
