- •
The critical temperature range of FSCs was 400–600 °C.
- •
The relationship between compressive strength and UPV was Weibull distribution.
- •
An exponential relationship between splitting tensile strength and UPV was observed.
- •
Compared to unheated FSC, the porosity value was more than trebled after exposure to 1000 °C.
- •
Svyatoslavite that was a new crystalline phase was observed at 1000 °C.
