The market demand for yttrium iron garnet (YIG) continues to release, and the future industry development prospects are broad

Yttrium iron garnet (YIG) is a garnet-type ferrite that belongs to the cubic crystal system. Yttrium iron garnet is a functional magnetic material, which can be divided into two types: yttrium iron garnet crystal and yttrium iron garnet single crystal film. Yttrium iron garnet has multiple advantages such as good gyromagnetic effect, high resistivity, small resonance line width, and low saturation magnetization. It is used in information storage materials, large-capacity optical fiber communication systems, laser modulators, magneto-optical isolators and other fields. widely.

The strong magneto-optical effect of yttrium iron garnet was first discovered by the American Bell Company in 1956. With the improvement of technical level and the deepening of research, the practical and commercialization level of yttrium iron garnet is gradually improving. Currently, the 131μm and 155μm near-infrared wavelengths are YIG magneto-optical isolator has reached the level of commercialization. In terms of growth technology, yttrium iron garnet can be grown through flux method, infrared thermal floating zone method, molten salt method and other processes.

According to the “2023-2027 Yttrium Iron Garnet (YIG) Industry In-depth Market Research and Investment Strategy Suggestion Report released by the Industrial Research Center 》 shows that in recent years, with the development of the optical and microwave industries, the global market demand for yttrium iron garnet magneto-optical materials has been continuously released, and the market size has shown a steady expansion trend, of which it will reach about 300 million yuan in 2021 and is expected to grow to 3.6 billion yuan in 2027. billion. From the perspective of market segments, yttrium iron garnet single crystal film is the mainstream product in the market, accounting for approximately 93.5% in 2021.

At present, the global yttrium iron garnet magneto-optical material market is still small, but the broad market prospects have still attracted a number of companies to actively deploy, including Germany’s Philips Hamburg Laboratory, the United States Isowave Company, Japan’s Oxide Company, and China’s Hefei Kejing Materials Technology Co., Ltd., etc. Among them, Philips Hamburg Laboratory of Germany is the world’s largest manufacturer of yttrium iron garnet.

Compared with European and American companies, my country’s yttrium iron garnet industry started late, and there are still certain gaps in technology, research and development, and application. However, as my country is a major manufacturing country, with the development of electronics, optics, microwave, display and other industries, the market demand for high-quality yttrium iron garnet will continue to grow. In addition, at the policy level, the country supports the development of high-quality yttrium iron pomegranate crystals and technology, and mentioned the need to achieve high-quality YIG crystal growth in the key project of “New Display and Strategic Electronic Materials”. Driven by both demand and policies, my country’s yttrium iron garnet industry has broad room for development.

Industry analysts said that as a magnetic material, yttrium iron garnet has the characteristics of good gyromagnetic effect and high resistivity. Applications in fields such as optics and microwaves are becoming more and more widespread. At present, the global yttrium iron garnet market is still small, and foreign companies occupy a major share of the market. However, with the development of my country’s economy, the market demand for yttrium iron garnet continues to grow. In the next five years, my country’s yttrium iron garnet market will remain Growth rates above the global average.
