SODIUM META SILICATE ANHYDROUS

Sodium Meta Silicate Anhydrous (Na2SiO3) is a powerful alkaline compound, commonly used across various industrial applications. Unlike its hydrated form, Sodium Meta Silicate Anhydrous is an anhydrous crystalline substance that contains no water molecules in its structure. It is typically white, odorless, and highly soluble in water, forming a strongly alkaline solution. Sodium Meta Silicate Anhydrous is valued for its ability to act as a buffering agent, water softener, and emulsifier. It is widely used in detergents, water treatment, and as a key component in various chemical processes.

• Sodium Silicate Solution: In some applications, Sodium Meta Silicate Anhydrous is dissolved in water to form a sodium silicate solution, which is used in chemical processes, including those for paper and textile industries.

7. Agriculture

• Pesticide Formulation: Sodium Meta Silicate Anhydrous is sometimes used as a carrier in pesticide formulations, where it helps improve the spreadability and effectiveness of the pesticide on crops.

8. Fireproofing

• Fire-Resistant Coatings: It is used to create fireproof coatings for materials such as wood, fabrics, and textiles. The compound helps to improve the fire resistance of these materials by forming a protective silica barrier when exposed to heat.

Safety and Handling

Hazards:

• Health Risks: Sodium Meta Silicate Anhydrous is a strong alkaline substance and can cause skin and eye irritation upon contact. Prolonged exposure or inhalation of dust may cause damage to the respiratory system. Ingestion can lead to severe burns to the digestive tract.
• Environmental Impact: Sodium Meta Silicate Anhydrous can be harmful to aquatic life if released into water bodies. It should be disposed of responsibly to minimize environmental contamination.

Precautions:

• Personal Protective Equipment (PPE):
  • Gloves: Use chemical-resistant gloves (e.g., nitrile or rubber gloves) to protect the skin.
  • Eye Protection: Safety goggles or face shields should be worn to avoid eye exposure to dust or splashes.
  • Respiratory Protection: Wear a suitable dust mask or respirator to avoid inhaling dust particles during handling.
  • Protective Clothing: Wear protective clothing, such as lab coats or aprons, to avoid skin contact.
• Handling and Storage:
  • Storage Conditions: Sodium Meta Silicate Anhydrous should be stored in a cool, dry place in tightly sealed containers, away from moisture and incompatible materials, such as acids.
  • Handling: Work with Sodium Meta Silicate Anhydrous in well-ventilated areas. Avoid direct skin and eye contact. Clean up any spills immediately to prevent hazards.

First Aid Measures:

• Inhalation: Move the affected person to fresh air immediately. Seek medical attention if symptoms persist.
• Skin Contact: Wash the affected area with plenty of water for at least 15 minutes. Seek medical attention if irritation persists.
• Eye Contact: Rinse eyes immediately with plenty of water for at least 15 minutes, holding the eyelids open. Seek medical attention.
• Ingestion: Do not induce vomiting. Rinse the mouth with water and seek immediate medical attention.

Disposal:

• Neutralization: Sodium Meta Silicate Anhydrous can be neutralized using a dilute acid (e.g., acetic acid or hydrochloric acid).
• Disposal Regulations: Follow local environmental regulations for the disposal of sodium compounds. Ensure that it is not released into water systems or the environment.
