摘要： A mold forming and molding technology operable to produce a silicon ingot suitable for obtaining a solar cell substrate is disclosed. A slurry is prepared comprising particles with surface oxide layers operable to bond the particles to each other. An external force is applied to the slurry to eliminate cohesion of the particles to form a de-cohesive slurry, and an inner surface of a mold base is coated with the de-cohesive slurry to form a releasing layer that reduces defects in the silicon ingot.
