By 300C, and in the presence of the released H2, the Ni particles have been reduced of their oxice and are sintered together into a spongy solid. It remains this way until the LiH and Al have melted, and then the web of SOLID spongy Ni is coated with a liquid film of LiH-Al . The Ni is solid and is not going to stir, however, it may be possible to get motion of the liquid LiH-Al metal.
