JX and OXIDE enter into capital and business alliance agreement
Tokyo-based JX Advanced Metals Corp and OXIDE Corp of Yamanashi, Japan (which specializes in optical crystals and frequency-conversion technology) have entered into a capital and business alliance agreement. JX plans to subscribe for shares to be issued by OXIDE through a third-party allotment and acquire shares representing 7.66% of OXIDE’s total issued shares. The investment is expected to amount to about ¥2.75bn, and JX’s ownership ratio is expected to be 7.12%.
JX operates globally, primarily developing, manufacturing and selling advanced materials made from copper and rare metals. The firm has positioned crystal materials as one of the pillars of its next-generation businesses. In response to the expansion of AI data centers and the growing use of optical communications within data centers, JX is investing up to ¥150bn over four years to expand production capacity for indium phosphide (InP) substrates. To further grow its crystal materials business, it is also pursuing developing and commercializing new materials and technologies through co-creation with external partners.
OXIDE operates in the photonics field, with optical single crystals and laser-related technologies as its core technologies. In addition to offering optical materials such as bismuth-substituted rare-earth iron garnet (Bi:RIG, used in optical isolators), OXIDE is also developing next-generation optical materials such as thin-film lithium niobate (TFLN) and expanding its business into quantum-related fields, including quantum communications and quantum computing.
Through the alliance, the two companies will combine JX’s materials development and mass-production technologies cultivated through its crystal materials business including InP substrates, its thin-film materials technologies and its global customer base with OXIDE’s optical single-crystal growth technologies, wavelength-conversion technologies, and optical-device and laser technologies. The companies will hence complement each other’s materials and technology portfolios.
Specifically, they aim to mutually leverage their expertise in mass-production technologies and manufacturing processes for crystal materials to further advance production technologies and mass-production capabilities, while also utilizing JX’s global customer base to expand their business reach. Furthermore, by drawing on their respective technologies and expertise in crystal materials, optical devices and lasers, the companies will work to create medium- to long-term business opportunities in fields such as optical communications and photonics-electronics convergence, semiconductors, and healthcare. They also aim to create new materials, products and businesses in quantum-related fields, including quantum communications and quantum computing.
Through the investment, the firms expect to strengthen their collaboration and accelerate technology development and commercialization by leveraging their respective strengths, hence expanding their business portfolios and achieving sustainable growth in the crystal materials and photonics fields.
