PBN, the full name of pyrolytic boron nitride, refers to boron nitride prepared through pyrolysis reaction at extremely high temperatures. It belongs to a category of advanced inorganic non-metallic materials. PBN purity is as high as 99.999%, colorless and odorless, white powder in appearance, with good density, high temperature resistance, insulation, oxidation resistance, air tightness, acid and alkali resistance, thermal shock resistance and thermal conductivity. .

The main production process of PBN is to use boron trichloride, ammonia, etc. as raw materials, and use chemical vapor deposition technology under high temperature and high vacuum conditions to prepare pyrolytic boron nitride through CVD reaction, cracking and other links. PBN products mainly include PBN crucibles, PBN sheets, PBN components, PBN coatings, PBN boats, etc.

PBN has a wide range of applications. In the field of semiconductor crystal synthesis, PBN is mainly used as a crucible in single crystal growth process scenarios such as the VGF method, VB method, LEC method, and HB method. It is currently the most popular semiconductor single crystal (gallium arsenide, indium phosphide, etc.) ) ideal container for growth; in the field of semiconductor epitaxial film making, PBN is mainly used as a source furnace container in molecular beam epitaxy growth process scenarios; in the field of semiconductor single crystal pulling, PBN is mainly used as an insulating material for graphite heater insulating coatings Installation scenarios; in the OLED field, PBN is mainly used as a guide ring and crucible in the evaporation element manufacturing scenario of the OLED evaporation system.

At present, semiconductors are the main application field of PBN materials, and PBN products play an indispensable role in the semiconductor field. In recent years, driven by the rapid development of the domestic semiconductor industry, PBN market demand has continued to increase and its scale has continued to expand. In 2021, the scale of my country’s semiconductor market has exceeded US$210 billion. Against this background, according to the“China PBN (Pyrolytic Nitridation) 2023-2027” released by the Industrial Research Center Boron) Industry Market Monitoring and Future Development Prospects Research Report shows that my country’s PBN market size has reached US$24 million in 2021. Among them, PBN crucible is the mainstream product in the PBN product market.

Companies currently in the PBN market mainly include Japanese Shin-Etsu Chemical, American Momentive Technology, British Morgan Advanced Materials, German Peters, American Stanford Advanced Materials, British Thermic Edge and other foreign-funded enterprises, as well as Guojing New Materials, Novartis Ceramics, Hefuxiang Ceramics, etc. Local companies and joint ventures such as Boyu Semiconductor. Among them, Boyu Semiconductor and Shin-Etsu Chemical are the two companies with the largest market share of PBN in my country in 2021, and the industry concentration is high.

Industry analysts personnel said that as a type of advanced ceramic material, PBN plays an indispensable role in the semiconductor field. Lack of effect. Currently, against the backdrop of the rapid development of the national economy and the continued boom in the electronic information industry, my country’s semiconductor industry is developing rapidly, which in turn has driven the increasing demand and expansion of the PBN market, and the industry has good development prospects. However, due to technical barriers, in the current domestic PBN market, local companies still occupy a small market share and the level of localization is low. In the future, local PBN companies will need to increase their efforts in technological research and product innovation, and there is huge room for industry growth.
