On Earth gravity causes Spacelab. convection currents, which pull cooler or heavier liquids downward. In microgravity these currents do not occur, so it is easier to grow larger, purer crystals for use as electronic components. There have been experiments in alloy and drug production to investigate the advantages of microgravity, but manufacturing in space will not be economical until there is a reduction in the cost of spaceflight.
