The technology and technology of the current sapphire furnace are controlled and implemented by GT, ThermalTechnology, RubIcon and other overseas companies. The GTAT sapphire furnace orders are about 1,500, of which 70% are in China.
Shenzhen Jinglaide Lighting Co., Ltd., which started with LED holiday lights, keeps pace with the times and boldly cuts into the field of sapphire crystal growth furnace, the most upstream of the LED industry. In 2011, Jinglaide announced that the sapphire crystal growth furnace equipment has been successfully tested. In June 2012, the 85 kg sapphire substrate furnace independently developed has entered the stability test period.
“Although our large-size sapphire crystal growth furnace project has achieved good results, it seems that we can 'pay' it, but we are not eager to push the market. This is still in the middle of the year, we are constantly researching and trying to get the crystal growth furnace as soon as possible. The finished product rate is the highest. Our goal is to produce a high-yield, truly commercial crystal growth furnace that can produce high-quality sapphire crystals in large quantities under standard operation." Liu Shichang, Delight Lighting Co., Ltd. said, "It is expected that for half a year, our large-size sapphire crystal growth furnace should be able to produce crystals of more than 100 kg in a stable and stable manner."
According to the person in charge of the relevant technology of Jinglaide, the key technology of the sapphire growth furnace is mainly concentrated on the design of the thermal field. In the design of the thermal field, Jinglande comprehensively considers the influence of heating elements, thermal protection, squatting, seed crystal heat exchanger and other aspects of thermal field components, through computer thermal field simulation, theoretical calculation, experience and experimentation. Accurately design temperature gradients to grow ideal sapphire crystals.
"A breakthrough in the large-size, large-kilometer sapphire crystal growth furnace will be a breakthrough in the development of China's core independent intellectual property equipment manufacturing industry," said Yu Shirong, director of the Guangdong Semiconductor Lighting Industry Joint Innovation Center. For the breakthrough in the realization of localized equipment, Liu Shiquan, the chairman of Shenzhen Jinglande Lighting Co., Ltd., is full of confidence: "The next step in the research and development of Jing Lande will be 200 kg crystal growth furnace."

Throughout the current sapphire crystal growth furnace market, the technology and technology of the sapphire crystal growth furnace are mainly controlled by foreign companies, and they have implemented technical blockade, and imported equipment has occupied a large share. The Chinese enterprises represented by Shenzhen Jing Lande broke through the technical blockade and made important contributions to the localization of sapphire crystal growth furnace equipment and made major breakthroughs.
