** Shares of Solvay SOLB.BR rise 3.4%, leading gains on Belgium's blue-chip BEL 20 .BFX index, after the chemicals company signed two deals to supply rare earth materials in the U.S.
** Solvay is partnering with U.S. firms Noveon Magnetics and Permag to supply rare earth oxides
** Even if they do not provide green light for a larger scale investment, the agreements show that interest in the space is heating up, says KBC Securities' Wim Hoste
** "Solvay is preparing for investing an additional 50-100 million euros ($58 million-$117 million) in rare earth capacities that could serve the permanent magnet market, but wants to secure long term commitments from customers before doing so," he says
** Including Thursday's move, shares of Solvay are down 10.7% this year
