Kaistar to fab LEDs with ultra-high-purity ammonia from LLH China

March 22, 2012 — Linde LienHwa (LLH) China will be the exclusive gas supplier to Kaistar, a joint venture of LED maker Epistar Taiwan and China Electronics Corporation (CEC). LLH China will deliver bulk gases and high-purity ammonia (NH3) to Kaistar’s new light-emitting diode (LED) production facility in Xiamen, China.

Kaistar’s new facility will be constructed near to Linde’s ultra-high purity ammonia plant in Xiamen, which was built in 2010 as the first operating plant in China to produce ultra-high purity ammonia. Ultra high-purity ammonia increases LED efficiency by eliminating oxygen, which can contain molecules such as moisture. Linde’s ammonia purification plant, which has an initial capacity of 500 tonnes per year, produces ultra-high purity ammonia at 7N (99.99999%) levels.
