Polycrystalline silicon ingot casting process based on boron nitride coating

The invention discloses a polycrystalline silicon ingot casting process based on a boron nitride coating. The process includes the first step of preparing a coating at the bottom of a crucible and the second step of conducting polycrystalline silicon ingot casting, wherein filling, preheating, melting, nucleating, and annealing and cooling are conducted in sequence, and the annealing and cooling step includes the substeps of primary annealing, wherein the heating temperature of a polycrystalline silicon ingot casting furnace is lowered to T4 and the temperature is kept for 2-3 h, and T4 is 1250-1280 DEG C; secondary annealing, wherein the heating temperature of the polycrystalline silicon ingot casting furnace is lowered to T5 from T4 and the temperature is kept for 2-3 h, and T5 is 900-950 DEG C; cooling. The process is simple in step, reasonable in design, easy and convenient to implement and good in use effect; by coating the bottom of the crucible with a layer of bottom coating with boron nitride as the main raw material, the oxygen content of the bottom of the crucible can be effectively reduced, the hard point of a finished ingot casting product can be effectively reduced, the annealing process is adjusted, and the quality of the finished ingot casting product can be improved.

Method for reducing bottom oxygen content of polycrystalline silicon ingot casting

The invention discloses a method for reducing bottom oxygen content of polycrystalline silicon ingot casting. The method comprises the following steps: 1, preparation of a crucible bottom coating, wherein a preparation process comprises: 101, preparing a coating spraying solution: uniformly mixing an organic grouting agent, de-ionized water and boron nitride at the mass ratio of 1 to (2 to 2.5) to (0.8 to 1.2) to obtain the coating spraying solution; 102, spraying: uniformly spraying the coating spraying solution on an inner bottom surface of a crucible by adopting spraying equipment and drying to obtain the bottom coating; 103, drying: drying the coating spraying solution sprayed on the inner bottom surface of the crucible by adopting drying equipment to obtain the bottom coating; 2, polycrystalline silicon ingot casting: carrying out the polycrystalline silicon ingot casting by utilizing the crucible with the bottom coating. The method disclosed by the invention is simple in steps, reasonable in design, simple and convenient to realize and good in use effect; one layer of the bottom coating taking the boron nitride as a main raw material covers the bottom of the crucible, so that the bottom oxygen content of the crucible can be effectively reduced, hard inclusion of an ingot casting finished product can be effectively reduced and the quality of the ingot casting finished product is improved.
