• Appearance: fine crystalline powder or irregular pieces of various shades of gray or yellow;
• The particle size is no more than 10 mm.;
• Mass fraction of total alkalinity in terms of Na2O, not less than 20.5%;
• Mass fraction of silicon dioxide SiO2 not less than 19.0%;
• Mass fraction of sesquioxides R2O3 is not more than 0.2%;

STORAGE:

Sodium metasilicate is stored in dry covered warehouses away from strong acids, metals, food and feed. Sacks with sodium metasilicate are stacked in a stack no more than 2 m high (8-9 rows) in a dressing.

Guaranteed shelf life is 12 months from the date of manufacture.
