Abstract: A manufacturing method for high-quality quartz crucible uses a vacuum arc method to melt, the positioning of the graphite electrode and dwell time at each position meet following requirements in which: taking a position of an upper end surface of a mold opening as a zero point, an end of the graphite electrode is marked as + when above the zero point, marked as ? when below the zero point; a starting position of the graphite electrode is +0.10˜0.30 times an outer diameter of the crucible, dwell time ?2 minutes, then the position is descended sequentially in accordance with a stepwise positioning method, staying for a period of time every time descending to a position, the graphite electrode continuously releases a high-temperature arc to melt crucible blank during a corresponding period of time at a corresponding position, and reaches a bottom polishing position after moving at least 3 times.
