White or slightly yellowish crystalline powder.
"Meta-vanadyl ammonium" is a crystalline powder that serves as a raw material for applications utilizing color and many compounds containing V. It is white or slightly yellowish, and when heated, it emits an ammonia odor, loses ammonia and water, and transitions from lemon yellow to reddish-brown, ultimately becoming a dark brown oxide after losing all ammonia. It slightly dissolves in cold water, hot ethanol, and methanol, and easily dissolves in warm water and ammonia water. 【Features】 ■ Raw material for applications utilizing color and many compounds containing V ■ Slightly dissolves in cold water, hot ethanol, and methanol ■ Easily dissolves in warm water and ammonia water ＼ For more details, please check by downloading the catalog ／
