A recent article in The Korean Times reported that with technological help from GT’s service installation team, OCI has already started exporting various sized sapphire cores to its customers. The article went on to say that GT’s ASF furnaces, which use the heat exchanger method (HEM) growth process, incorporate a cost-effective sapphire crystallization methodology for the high yield production of quality material.
