A study has been made of the temperature field in an AlZn eutectic melt for a Bridgman‐Stockbarger arrangement of the experiment. The influence of the sizes of the ampoules and corundum inserts for the temperature measurements on the final temperature field in the specimen has been studied for different angles α contained by the gravity and the axial temperature field gradient vectors in the specimen. It has been found that an axially located corundum insert increases the convection intensity to a maximum at angles α between 45 and 60°. An influence of the insert for α = 0° is almost negligible.
