Method of fabricating a turbine engine part

A method of fabricating a turbine engine part, the method comprising:

• fabricating an ingot out of ceramic material of eutectic composition by performing the Czochralski process comprising the following steps:
• putting a seed of the ingot that is to be obtained into contact with a molten bath of a mixture of eutectic composition in order to initiate the formation of the ingot on the seed, said mixture comprising at least two ceramic compounds;
• drawing the ingot from the molten bath while imposing on the ingot that is being formed a drawing speed less than or equal to 10 mm/h together with rotation at a speed of rotation less than or equal to 50 rpm;
• and
• machining the ingot as fabricated in this way in order to obtain the turbine engine part,
• wherein the ingot is drawn from the molten bath along a drawing axis, and wherein a temperature gradient less than or equal to 50° C./mm is maintained in the ingot along the drawing axis, at least in the vicinity of a surface of the molten bath.
