“We were delighted to be part of HTOT’s celebration commemorating their official entrance into the sapphire material industry,” said Tom Gutierrez. “Over the coming months we will work closely with the HTOT team to ensure a smooth ramp to volume production in their new state-of-the-art facility, which incorporates our ASF crystal growth equipment. In their initial production runs, HTOT has successfully grown four high quality boules, all of which were over 100 kilograms.”

Gutierrez continued, “GT has a proven track record of partnering with companies to accelerate their entry into new markets by giving them the tools and support they need to become key industry players. Over the next few months we expect several of our other key sapphire customers in Asia to start producing sapphire and we look forward to working with these customers to ensure their smooth entrance into the sapphire growth industry.”

In the six months since the announcement, HTOT has built a state-of-the-art production facility and is in the process of completing the installation of equipment and ramping to volume production.
