The effect of various molarity sodium hydroxide (NaOH) on the hydrosodalite formation from synthesis of Johor Kaolin, Malaysia by hydrothermal method
In this present work, hydrosodalite was successfully synthesized by hydrothermal method from the raw Johor kaolin, Malaysia. In order to get the size that was less than 63 lm, the raw kaolin was ground and sieved. Since the raw kaolin did not undergo the beneficiation process, thus the raw kaolin...

| description | In this present work, hydrosodalite was successfully synthesized by hydrothermal method from the raw
Johor kaolin, Malaysia. In order to get the size that was less than 63 lm, the raw kaolin was ground and
sieved. Since the raw kaolin did not undergo the beneficiation process, thus the raw kaolin then was
calcinated for four hours at 650 �C to produce more reactive clay (metakaolin). The synthesizing of
hydrosodalite form of the metakaolin powder was conducted by mixing the powder with different molar�ities of sodium hydroxide, NaOH. This mixture was further treated by soaking it at a temperature of 40 �C
for 24 h. The reaction mixture was then moved for 12 h into the autoclave for the 100 �C under hydrother�mal conditions. The results through phase analysis via XRD, microstructure observation via SEM and
bonding analysis via FTIR has revealed the existence of hydrosodalite phase in comparison with pure kao�lin and metakaolin. The result also indicated the lower NaOH (4 M) molarity gave a higher percentage of
hydrosodalite formation in comparison with higher molarity of NaOH at 5 M, 6 M and 7 M. |
