Sample Preparation, User Instructions and Precautionary Measures
Instruction for Sample Preparation
- Sample should be well polished and having smooth surface.
- Maximum of six samples will be accepted at a time for room temperature.
- Maximum of two samples will be accepted at a time with temperature measurement.
- Maximum sample dimension should be diameter of 3 cm and thickness 0.3 cm for Low frequency, and diameter 1 cm and 0.2 cm thickness for RF
- After applying silver paste (Conducting coating) to ceramics samples it should be heated at 150oC at least for one hour.
- User has to bring liquid nitrogen.
- Only one registration will be accepted at a time.
User Instructions and Precautionary Measures
- Payment Mode: Payment should be made in advance by a Demand Draft (DD) drawn in favour of “The Registrar, IIT Bombay, P and C Account".
