摘要

A process for the preparation of a sic - bulk single crystal (2), whereina) of the sic - volume single crystal (2) in the case of a growth temperature of up to 2200°C. by means of a sublimation growth process is produced,b) of the sic - volume single crystal (2) according to the sublimation growth, is thermally treated on a finishing temperature, which is higher than the growth temperature has been reached, is brought, andc) of the sic - volume single crystal (2) before the thermal aftertreatment within a sic - powder (19) is placed, and during the thermal aftertreatment completely from the sic - powder (19) is surrounded.
