Aim and Objective:
This study explains the FT-IR, XRD, XRF, SEM/EDX, TGA, and
DSC/DTA characterization of commercially available kaolin clay. The objective of this paper is to
explore the prominent utilization of kandites clay and useful chemical aspects for the modification
of kaolin clay minerals.
Materials and Methods:
The untreated kaolin sample has been procured in this experimental work
from AksharChem, Gujrat, India. The kaolin clay was treated with 4M hydrochloric acid. FT-IR,
XRD, XRF, SEM/EDX, TGA, and DSC/DTA characterization methods have been used.
Results:
Loss on ignition was found at 10.89%. The fingerprint region of the acid-treated sample
has broad and more bending vibrations than untreated samples. The high weight percentage of Ti
and CaCO3 were spotted in the scanning electron micrograph by both atomic % and weight %. The
FT-IR revealed the functional group of Al-O, A1-OH, and Si-O.
Conclusion:
The morphology indicates that the presences of large particles are in the form of
agglomerates. It was found that impurity like scandium vanished and manganese traced by the
same atomic % 0.01 of zinc which had no presence after acid treatment. Thermogravimetric
analysis indicates the sharp increments in heat flow in-between temperatures 0°C to 200°C and
consequently increments in between 500°C to 550°C, a suitable range for the pyrolysis. Low
amount of alumina and high amount of silica has been found out. TGA and DTA analysis satisfy
the waste plastic valorization temperature ranges.
