Deuterated Ammonia: Establishment of Japan’s First Mass Production System

Taiyo Nippon Sanso has started manufacturing and selling deuterated ammonia (a high-pressure gas), where the hydrogen in ammonia (NH3) is replaced with deuterium (D). Previously, Japan relied on imports from foreign countries to meet demand for deuterated ammonia, which is used in semiconductors, chemical reaction materials, and analysis applications. With our proprietary technology, we have successfully built a process capable of producing high-purity, high-deuterium-concentration products, establishing Japan’s first mass production system and putting into place a supply system to meet growing global demand for deuterated ammonia. We will continue to increase production in anticipation of future growth in demand.
