Disintegration curse

This spell (incantation unknown) is a curse that causes the person who is hit, to burst into small pieces and desintegrate.

Behind of scenes

 * This spell only makes an appearance in Harry Potter and the Deathly Hallows: Part 2, in which Molly Weasley uses it to finish off Bellatrix Lestrange. In the novel, Bellatrix is hit by a curse squarely in the chest, her eyes bulge and her body topples lifelessly to the ground.
 * On the other hand, many fans depict it as a Petrificus Totalus combined with a Blasting Curse. A statue blown to pieces, as it seems.
