Description

General description

Glassy carbon shows only short range order in its structure. Photoacoustic doppler effect from the suspension of spherical carbon particles was investigated. Glassy carbon exhibits a specific conductivity of 700Scm^-1. 4

Application

Amorphous carbon may be used to develop zero temperature coefficient of resistance (TCR) based systems. Glassy carbon has been used as a catalyst support for bimetallic Rh–ReO_x. It may be used to enhance the accuracy of infrared (IR) surface temperature measurements on micro-electro-mechanical systems (MEMS).
