The market size of arsane (arsenide) continues to grow, and the production capacity of local companies continues to expand.

Arsane, also known as arsine and arsine, has the chemical formula AsH3 and is the simplest arsenic compound. Arsenane appears as a colorless gas, and when oxidized by air, it will produce a slight garlic-like smell. It is soluble in chloroform, benzene and water, and slightly soluble in alkali and ethanol. Arsane has the characteristics of good chemical stability, flammability, and decomposition, and is widely used in industrial production, semiconductor manufacturing, optoelectronics, photovoltaic power generation, satellite communications, national defense and military industry and other fields.

The main preparation methods of arsenane include dilute hydrochloric acid decomposition method, ether solution reaction method, arsenic metal compound and water or acid reaction method, etc. Purification is a key link in arsane production. Membrane separation, adsorption and distillation are the main purification methods. The purity of arsane produced using membrane separation can reach more than 99%, but its technical difficulty is high and it has not yet been used in my country. Achieve large-scale applications. After years of experience accumulation, my country’s arsane production technology has continued to make breakthroughs, but purification technology still cannot meet the demand for high-purity arsane production, which is a major challenge facing the development of the industry.

Arsane is one of the special electronic gases and is widely used in industrial production, semiconductor manufacturing, optoelectronics, photovoltaic power generation, satellite communications, national defense and military industry and other fields. In the field of semiconductor manufacturing, arsane can be used in the doping process of integrated circuit manufacturing; in the field of optoelectronics, arsane can be used in the LED chemical vapor deposition process; in the field of photovoltaic power generation, arsane can be used to manufacture high-efficiency solar cells. Benefiting from the accelerated development of downstream industries, the arsane market space continues to expand. In 2022, my country’s arsane market size will reach 86.913 million yuan, a year-on-year increase of 8.9%.

According to the “2023-2028 China Arsane (Arsenide) Industry Market In-depth Research and Development Prospects Forecast Report》shows that my country’s arsane production capacity will reach 52 tons in 2022, accounting for nearly 40% of the world’s total production capacity. At present, due to factors such as stricter environmental protection policies, the number of arsane production enterprises in my country is small and the production capacity is low. It is expected that in the future, with technological advancement, my country’s arsane industry will gradually develop in a green and environmentally friendly direction, and its production capacity will be increased by then.

In terms of market competition, my country’s arsane industry is highly concentrated, with leading companies occupying a dominant position in the market. Nanda Optoelectronics, Zhengfan Technology, Huawei Electronics, Walter Gas, etc. are the main manufacturers of arsane in my country. Nanda Optoelectronics Company’s annual production capacity of high-purity arsane has reached 30 tons. In November 2022, the company invested 80 million yuan in an annual production of 140 tons of high-purity phosphane, arsane expansion and arsane technical transformation projects.

Industry analysts said that as a special electronic gas, arsane is widely used in many fields. In the future, with the gradual release of downstream demand, my country’s arsenic The development speed of the alkane industry will further accelerate. In recent years, my country’s arsane production capacity has been low due to factors such as environmental policy restrictions and high technical barriers. It is expected that in the future, as local companies continue to exert their efforts, the development speed of my country’s arsane industry will further accelerate.
