(Yicai) Oct. 25 -- Shares of Hubei Heyuan Gas rose after the Chinese company said Jinko Solar Holding, a leading solar panels maker, had placed a CNY600 million (USD82 million) order for electronic gases.

After earlier soaring by the 10 percent daily trading limit, Heyuan Gas [SHE: 002971] closed 2.6 percent up at CNY24.07 (USD3.29) a share today.

Heyuan Gas recently penned a long-term supply deal with the plant of Jinko Solar's Shangrao branch in Jiangxi province, the Yichang-based firm said late yesterday. From next month to December 2025, the firm will provide the factory and its associated companies with high-purity electronic-grade ammonia and electronic-grade silane gas.

The Jinko Solar deal will accelerate the entry of Heyuan Gas' electronic gases into the solar industry, the firm said, without disclosing further details.

Ammonia gas is a raw material used to produce silicon nitride. Adding silicon nitride and silane in solar batteries can improve photoelectric conversion efficiency and increase stability.

Heyuan Gas is a new player in the electronic gases sector, investing in and building two factories in Qianjiang and Yichang, both in Hubei province. Its high-purity electronic-grade ammonia gas production facility at Qianjiang began trial operations in August, and that for producing electronic-grade silane gas in Yichang is likely to become operational next year, the firm noted.
