A series of deuterated ADP crystals were grown from deuterated aqueous solution by point-seed rapid growth method in this paper. The specific heat, thermal diffusivity and thermal conductivity were examined with a simultaneous thermal analyzer and a laser thermal conductivity meter, respectively. The experiment results show that the specific heat improve with increasing deuterated level in ADP crystal (60% partially deuterated, 1.62 J/(g*C), 120 ^oC) which is superior to that of 74% partially deuterated KDP crystal (1.21J/(g*C), 120 ^oC). However, (100) and (001) directions of thermal diffusivity and thermal conductivity present different variation trends and have no significant variation with deuterium doped.
