Focus on high purity ammonia gas

The High Purity Ammonia (HPA) is one of the primary indirect material for Photoelectron and Microelectronics Technology, mainly for producing high-quality nitrides, such as GaN and Si3N4. It is widely used in the manufacture of LED, Solar Cells (PV), LCD, IC, etc.
As a safe and cheap source of fixed nitrogen, the demand for HPA has increased dramatically because of the prosperity of the photovoltaic (PV) and the light-emitting diode(LED) industries.
