 Silicic acid, beryllium salt (CAS NO.15191-85-2) is also called Beryllium orthosilicate ; Beryllium silicate (Be₂SiO₄) ; Beryllium silicic acid ; Beryllium silicon oxide (Be2SiO4) ; Diberyllium monosilicate ; Beryllium orthosilicate . Silicic acid, beryllium salt (CAS NO.15191-85-2) is high toxic. So the storage environment should be ventilate, low-temperature and dry.
