Parameters Expediting the Thermal Conversion of Ba-Exchanged Zeolite A to Monoclinic Celsian

Table 1

Thermal treatments done to all four Ba-exchanged zeolite A samples and the figures in which the corresponding XRD patterns are shown.

Temp (°C)	Thermal treatment^a (h)
200	2 (Figure 1(a))
500	0 (Figure 1(b))
800	28 (Figure 1(c))
1000	5 (Figure 2)
1100	5, 10
1200	5
1300	5 (Figure 3), 10, 15
1400	5
1500	5

^aThe samples were heated at a rate of 10°C/min up to the reported temperature, kept at that temperature for the reported time, and allowed to cool in air.
