Anhydrous sodium metasilicate (CAS 6834‑92‑0) supplied by Global Optimals is a high‑purity granular product. It contains Na₂O 50.8 % and SiO₂ 49.2 %, delivering a pH ≈ 12.5 in a 1 % aqueous solution, which makes it an effective alkaline cleaner and metal corrosion inhibitor. Metasilicate belongs to the family of alkaline silicates that form robust gel networks when they interact with hydroxide ions, providing both high alkalinity and a protective silicate film on metal surfaces. This film not only raises the pH but also complexes cations, reducing aggressive species that drive corrosion. The granules disperse readily in automated dosing equipment, allowing precise control in industrial cleaning, heavy‑duty degreasing, and surface passivation processes. In concrete and mortar mixes, metasilicate acts as a silicate binder, enhancing particle adhesion, increasing compressive strength, and improving resistance to moisture ingress, which is especially valuable for high‑performance concrete, precast elements, and waterproofing applications. When combined with admixtures such as plasticizers, super‑plasticizers, or microsilicates, it promotes better dispersion and stabilizes the microstructure of the final product. In animal feed, the silicate provides a bioavailable source of silicon that supports bone mineralization and connective‑tissue health, provided that recommended inclusion levels are observed. Practical handling guidelines include using protective gloves and goggles, ensuring adequate ventilation, and storing the material in a dry, well‑ventilated area at 15‑25 °C. The product is supplied in 25 kg polyethylene bags that protect granule integrity. Solubility can be tuned by adding the material as a dry powder or by pre‑dissolving it in a small volume of water, allowing flexibility in formulation. Full technical documentation – Technical Data Sheet (TDS), Safety Data Sheet (SDS) and Certificate of Analysis (COA) – accompanies each batch, ensuring traceability and consistent performance across a wide range of industrial applications.

Store anhydrous sodium metasilicate in a dry, well‑ventilated area protected from moisture and direct sunlight. Recommended storage temperature ranges from +5 °C to +30 °C; higher temperatures may cause granule agglomeration. Shelf life is typically 24 months when packaging remains intact. Use protective gloves, safety goggles and respiratory protection during handling, avoiding skin contact and inhalation of dust. Ensure the polyethylene container is undamaged and free of leaks before use.
