A theoretical study of the radiative heat transfer inside art uniaxial dich
roic non optically active crystal is presented. The general equations which
govern the thermal problem are established for absorbing moderately crysta
ls. The temperature and radiative flux fields at radiative equilibrium show
the thermal effects due to the anisotropy inside the medium. (C) 2000 Acad
