Beryllium Metaphosphate Definition

A white colored, crystalline, inorganic compound that emits toxic fumes of beryllium oxides and phosphorus oxides upon heating. Beryllium metaphosphate is used in small amounts for special ceramic compositions and as a catalyst in organic reactions. Inhalation exposure to its dust irritates the nose, throat and lungs and can cause pneumonitis. Prolonged exposure can result in a chronic beryllium disease called berylliosis causing granuloma and fibrosis formation in the lungs. Beryllium is associated with an increased risk of developing lung cancer. (NCI05)
