在900 ~ 1500℃的温度范围内，测量了层状热解碳的氚扩散系数和氘溶解度。在相同温度下，氚扩散系数远低于金属，但扩散的活化能要高得多（~ -100 kcal/mol）。硅掺杂热解碳的氚扩散系数比未掺杂层状热解碳的氚扩散系数高一个数量级以上。氘在层状热解碳中的溶解度随着温度的升高而降低，并表现出p. 12的压力依赖性
Tritium diffusion coefficients and deuterium solubilities have been measured for laminar pyrolytic carbon in the temperature range 900–1500° C. The tritium diffusion coefficients were much lower than those for metals at equivalent temperatures, but the activation energy for the diffusion was much higher (∼-100 kcal/mole). Tritium diffusion coefficients measured for silicon-doped pyrolytic carbon were over an order of magnitude higher than the values for the undoped laminar pyrolytic carbon. The solubility of deuterium in laminar pyrolytic carbon was found to decrease with increasing temperature and exhibited a pressure dependence of p. 1 2
