On gas uptake of coated and bare graphite during exposure to air
Description
The gas release of carbon probes from different manufacture and the gas-uptake during air exposure was investigated. Sealing of graphite with pyrocarbon (CVD) does not reduce the short-time gas-uptake in 1 to 2 days, but slows down the farther gas-uptake in one case but not in another one. Also the mass-spectroscopic investigation of desorbed species shows large differences in the composition and in the desorption temperature at equal weight loss
