文摘
- •
Ca incorporated layered silicate KHSi2O5 is hydrothermally synthesized directly.
- •
Effects of sol composition and reaction temperature on products are investigated.
- •
Perfect Ca–KHSi2O5 with Ca/Si of 0.15 is prepared at 493 K for 5 days in high yield.
- •
Altered intensity and shifted position of the XRD peaks imply the Ca incorporation.
- •
The presence of band indexed to Si–O–Ca in FTIR confirms the incorporation.
