  India-based Neutrino Observatory (INO) is a planned neutrino experiment to be
build up in southern part of India.The INO observatory will host a 51 kton Iron
Calorimeter (ICAL) detector to detect atmospheric neutrinos. Resistive Plate
Chamber (RPC) has been chosen as the active detector element for the ICAL
experiment. The ICAL experiment will consist of about 28,000 RPC's of dimension
$2~m\times 2~m$, divided into three modules. The experiment is planned to take
data at least for 20 years from its start date. Due to the large number of RPC
needed for ICAL experiment and the long lifetime of the experiment, it is
necessary to carry out detailed $R\&D$ to optimise each and every parameter of
the detector performance. We report on the performance studies carried out on
the RPC's made with these electrodes, and finally compare the detector
performance with that of the material properties to optimise the detector
parameters.
