There are many phosphine (PH3) manufacturers in my country, and the microelectronics field is its emerging demand end.

Phosphine (PH3), also known as phosphine and phosphine, is an inorganic compound. Phosphine appears as a colorless and odorless gas, soluble in ether and ethanol, and slightly soluble in water. Phosphine is flammable, highly toxic, and highly reducing, and is widely used in fumigants, microelectronics and other fields. According to different uses, phosphine can be divided into two categories: industrial grade phosphine and electronic grade phosphine.

​ ​ ​ Yellow phosphorus is the main raw material of phosphine, accounting for nearly 30% of its production cost. Affected by factors such as restrictions on national environmental protection policies and the deepening of supply-side structural reforms, my country’s yellow phosphorus production has shrunk significantly and will not gradually pick up until 2021. In 2022, my country’s yellow phosphorus output will reach 863,000 tons, a year-on-year increase of 19.9%. Guizhou, Yunnan, Sichuan, Hubei and other places are the main yellow phosphorus producing areas in my country. It is expected that my country’s yellow phosphorus market will still be in short supply for some time to come, which will bring certain challenges to the development of the phosphine industry.

Phosphine is toxic and flammable. Mass production can easily cause environmental pollution and harm human health. Its market share in my country is low. In recent years, phosphine, as a special gas, has gradually been widely used in the field of electronic manufacturing. In December 2021, the Ministry of Industry and Information Technology issued the “Guidance Catalog for the First Batch Application Demonstration of Key New Materials (2021 Edition)”. The document clearly included phosphine with a purity of ≥99.9999% into the catalog of new electronic chemical materials. In this context, my country’s high-purity phosphine will gain broad market space.

According to the “2023-2028 China Phosphine (PH3) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》 shows that phosphine is widely used in fumigants, microelectronics and other fields. Fumigants are the traditional application areas of phosphine. Phosphine fumigants are highly effective pesticides and can eliminate pests in ship cabins, fur warehouses and granaries. The field of microelectronics is an emerging demand end for phosphine, which can be used as a dopant to produce N-type semiconductors. In recent years, with the accelerated development of my country’s microelectronics industry, the market demand for phosphine has increased.

In terms of market competition, there are many phosphine production companies in my country, including Tongling Zhengfan Electronic Materials Co., Ltd., Dongguan Sanxin Industrial Gas Co., Ltd., Jiangsu Nanda Optoelectronic Materials Co., Ltd., Shanghai Zhengfan Technology Co., Ltd., etc. Zhengfan Technology is my country’s leading phosphine enterprise. It focuses on the research and development, production and sales of electronic specialty gases. Currently, the company is vigorously promoting the phosphine production expansion project.

​​  Industry analysts said that phosphine, as an electronic specialty gas, is in strong demand in the field of microelectronics. In recent years, benefiting from national policy support and the continuous improvement of the technical level of local enterprises, the development trend of my country’s phosphine industry has gradually improved. In terms of market competition, attracted by market prospects, the number of phosphine production companies in my country has increased. It is expected that high-purity phosphine will become the mainstream product in my country’s phosphine market in the future.
