文摘
- •
Evidence of mineralogical transformations is presented in unprecedented level of detail.
- •
β-Spodumene formation results in increased surface area and reduced particle size and SG.
- •
XRD spectra provide evidence of γ-spodumene formation between 950 °C and 1100 °C.
- •
Structural change first observed at 950 °C after 30 min are completed at 1100 °C in 10 min.
