Production Method of Tin Oxide SnO2 Powder

1. Chemical Precipitation

Mix tin chloride (SnCl₄) solution with sodium hydroxide (NaOH). This forms tin hydroxide (Sn(OH)₄) precipitate. Filter and wash the precipitate, then heat it at 400–600°C. The reaction is:

SnCl₄ + 4NaOH → Sn(OH)₄↓ + 4NaCl

Sn(OH)₄ → SnO₂ + 2H₂O

This method is simple and cost – effective for producing SnO₂ powder.

2. Sol – Gel Process

Dissolve tin alkoxide (like Sn(OEt)₄) in alcohol. Add water to start hydrolysis. Stir to form a sol, then let it become a gel. Dry the gel and heat it at 500–800°C. This gives nanoscale SnO₂ powder with uniform particles.

3. Vapor Deposition

Heat tin metal in a high – temperature chamber with oxygen gas. Tin reacts with oxygen to form SnO₂ vapor, which cools and turns into powder. This method is used for making high – purity SnO₂.

4. Hydrothermal Synthesis

Mix tin salts (such as SnCl₄) with water in a sealed container. Heat it under pressure (150–250°C). This directly forms crystalline SnO₂ powder. The process controls particle size and shape well.

Each method has its own uses. Precipitation and sol – gel are good for bulk production. Vapor deposition and hydrothermal methods make high – quality powders for electronics or sensors.
