Refractory Specialities has emerged as a solution to lowering the cost of making solid oxide fuel cells (SOFCs), while increasing their quality. It's done this by developing kiln products and a new coating that ensure very exact production of ceramic parts used in SOFCs. Based in Sebring, the company developed its new product line, SinterLyte, with the help of a $400,000 grant from the Ohio Third Frontier. Projections for the line expected revenues to surpass $25 million within four years. That means expected growth for RSI as well, which at the end of 2010 had more than 100 employees at two sites, and served more than 30 major clients and hundreds of smaller ones.  SinterLyte's success could earn RSI a large share of the global market.
