Abstract

We have developed a system for in-situ observation of glass melts under high magnetic field up to 10 Tesla. Thermal convection in a potassium phosphate melt was observed under vertical and horizontal magnetic fields. The velocity of convection decreased to one-third of the initial velocity at above 1 Tesla. It was deduced that different electro-magnetic forces act on positively charged alkali metal ions and negatively charged clusters consisting of PO₄ tetrahedra in the melt resulting in the reduction of total velocity of the melt above 1 Tesla.
