Investigations on heat conductivity and electrical resistivity of tungsten single crystals were started in 1936 with measurements on two tl~n crystals. Results on these crystals are given in this paper.
Using a single crystal with its a:ds parallel to the (1, 1, 1)direction, we failed in sepm'atingthe heat conductivit T into the lattice and electronic components by applying strong magnetic fields. Another single crystal parallel to the (I, 0, 0) direction was investigated down to 1.5Β°1K, and in. the liquid hydrogen region strong magnetic fields up to 36 kO were also applied. It showed large anisotropy amounting to 1.59. Results are given.
