DMC2 had been acquired by OMG from Degussa AG in April for $1.1 billion, and OMG at that time also announced an agreement to sell parts of the business to Ferro.
The operations acquired by Ferro have annual sales of $520 million and include 22 plants worldwide. The businesses manufacture materials used in ceramic capacitors and other electronic components; colorants for tile, dinnerware and paints; glass; and ceramic glazes.
Ferro is a major powder coatings producer and also manufactures ceramic glazes and specialty chemicals.
