High Purity Metastannic Acid

Updated: 2026-07-15

Overview

High purity metastannic acid, also known as stannic acid, is an inorganic compound derived from tin. It is widely used in industrial applications due to its high thermal stability and refractory properties. The compound is typically produced by reacting tin salts with alkaline solutions, followed by purification to achieve high purity levels suitable for specialized uses. In the B2B sector, high purity metastannic acid is a critical raw material for industries requiring precise chemical formulations. Its non-toxic nature and stability make it a preferred choice for applications in ceramics, glass, and electronics manufacturing.

Physical and Chemical Properties

High purity metastannic acid appears as a fine white powder with a density of approximately 4.5 g/cm³. It is insoluble in water but can dissolve in acidic solutions, making it useful for chemical synthesis. The compound decomposes at high temperatures without melting, which contributes to its stability in high-heat applications. Key chemical properties include its resistance to oxidation and its ability to act as a catalyst in certain reactions. These characteristics are leveraged in industrial processes where thermal and chemical stability are paramount.

Main Applications

The primary use of high purity metastannic acid is in the ceramics industry, where it serves as a glaze opacifier and flux. Its high thermal stability ensures that ceramic products maintain their integrity under extreme conditions. Additionally, it is used in glass manufacturing to improve durability and refractive properties. In the electronics industry, metastannic acid is employed in the production of conductive pastes and capacitors. Its refractory nature makes it ideal for components that require long-term reliability under thermal stress.

Safety and Storage

While high purity metastannic acid is generally non-toxic, precautions should be taken to avoid inhalation of dust particles. Workers should use protective gloves, masks, and goggles when handling the compound. Proper ventilation is also recommended to minimize exposure. Storage conditions are critical to maintaining the compound's integrity. It should be kept in a cool, dry environment, away from moisture and acidic substances that could degrade its quality. Sealed containers are preferred to prevent contamination.

B2B Procurement Guide

When procuring high purity metastannic acid, B2B buyers should prioritize suppliers with verified certifications and a track record of quality control. Purity levels should be confirmed through independent testing, especially for applications requiring stringent specifications. Price negotiations should consider bulk purchase discounts, but buyers must balance cost with quality. Shipping and storage logistics should also be evaluated to ensure the product arrives in optimal condition. Long-term supplier relationships can provide stability in pricing and availability.
