Application of Tellurium Oxide TeO2 powder

Production Method of Tellurium Oxide TeO2 Powder

1. Direct Oxidation

Heat tellurium metal in the air at 400–600°C. Oxygen reacts with Te to form TeO₂. The reaction is:

Te + O₂ → TeO₂. Grind the solid product into powder.

2. Acid Reaction

Mix tellurium with concentrated nitric acid. They react to form telluric acid (H₆TeO₆). Filter and wash the acid. Heat it at 300–400°C to decompose:

H₆TeO₆ → TeO₂ + 3H₂O. Collect the powder.

3. Hydrothermal Synthesis

Dissolve tellurium dioxide in NaOH solution. Add hydrogen peroxide. Heat the mixture in a sealed container at 150–200°C. Crystals of TeO₂ form. Filter and dry them.

4. Sol-Gel Process

Mix tellurium alkoxide (e.g., Te(OC₂H₅)₄) with ethanol. Add water to hydrolyze. Gel forms over time. Dry and heat at 400–500°C to remove organic parts.

5. Chemical Precipitation

Add ammonia to a tellurium chloride solution. A hydroxide precipitate forms. Wash and heat it to get TeO₂.

Storage Condition of Tellurium Oxide TeO2 Powder

1. Sealed Containers

Keep TeO₂ powder in tightly closed plastic bags or glass jars. This stops moisture and air from getting in, which can cause clumping or chemical changes.

2. Dry Place

Store it in a dry area with humidity below 40%. If needed, add desiccants to the container to absorb extra moisture. Wet conditions can slowly dissolve TeO₂ and ruin its quality.

3. Cool Temperature

Keep the powder at room temperature (15–25°C). High heat over 700°C can break down TeO₂ into tellurium and oxygen.

4. Avoid Reactive Substances

Keep TeO₂ away from acids, bases, and strong oxidizers. These materials can react with TeO₂ and change its properties.

5. Safe Handling

Use gloves and clean tools when touching the powder. Avoid breathing in dust or letting it touch your skin.
