The market demand for lanthanum aluminate single crystal (LaAlO3) is vast and my country’s production capacity needs to be improved.
Lanthanum aluminate, with the chemical formula LaAlO3, is a perovskite structure ABO3 compound. It has the advantages of wide energy gap, large specific surface area, small dielectric constant, low dielectric loss, small thermal expansion coefficient, and good thermal stability. Lanthanum aluminate single crystal is a type of high-temperature superconducting thin film substrate single crystal material made of lanthanum aluminate as a base material. It belongs to the hexagonal crystal system, with a melting point of 2080°C and a Mohs hardness of 6.5. It is an important type of lining. bottom material. According to different processing methods, lanthanum aluminate single crystal can be divided into single polished lanthanum aluminate single crystal and double polished lanthanum aluminate single crystal.
On the basis of inheriting the advantages of lanthanum aluminate, lanthanum aluminate single crystal also has the advantages of large size, good thermal sensitivity, low microwave loss, and strong chemical stability. It is comparable to high-temperature superconducting materials such as YBaCuO (ion sprayed yttrium barium copper oxide). With good lattice matching, it has become an important type of industrialized, large-size thin film substrate single crystal material in the market. It can be used in high-temperature superconducting microwave electronic devices, optical materials and components, dielectric resonance, fuel cells and other production scenarios, terminal Application fields include electronics, automobiles, industry, communications, aerospace, national defense, etc.
According to the 《2023-2028 aluminum The lanthanum acid single crystal (LaAlO3) industry market in-depth research and investment prospect forecast analysis report》 shows that the downstream of lanthanum aluminate single crystal Products mainly include microwave tunable devices, pyroelectric infrared detectors, high-temperature superconducting microwave filters, etc. Take pyroelectric infrared detectors as an example. It is a type of advanced infrared sensor that has been widely used in fire protection, monitoring, security and other fields. In 2022, the domestic pyroelectric infrared detector market size will reach 1.63 billion yuan. As a key component for manufacturing pyroelectric infrared detectors, the market demand for lanthanum aluminate single crystal is increasing, and the industry has broad prospects for development.
The technological threshold for lanthanum aluminate single crystal is relatively high. Currently, domestic companies in this field mainly include Hefei Single Crystal Materials Technology, Hefei Yuanjing Technology Materials, Hefei Horida Optoelectronic Materials, Hefei Kejing Materials Technology, and Anhui Keruisi Chuang Crystal Materials, Dalian Qiushi Crystal Materials, Beijing Tebowande Technology, etc. There are many companies, but most of them are small and medium-sized enterprises. In the future, my country’s lanthanum aluminate single crystal production capacity needs to be improved, and the industry has huge room for growth.
Industry analysts said that lanthanum aluminate single crystal is the most versatile method for the epitaxial growth of superconducting thin films. Crystal-like substrate materials play an important role in the production of high-temperature superconducting microwave electronic devices, optical materials and components, dielectric resonance and other materials and devices. In recent years, driven by the rapid development of the domestic microwave communication devices, thermoelectric electronic devices, and superconducting electronic device markets, the market demand for lanthanum aluminate single crystal has continued to increase, and the industry has shown good development prospects. At present, there are a large number of lanthanum aluminate single crystal manufacturers in my country, but due to technical limitations, the production capacity is still at a low level. In the future, local enterprises will need to increase technology research and development to promote the continuous improvement of enterprise production capabilities.
