Titanium Dioxide Formula-A Wafer Of Titanium Dioxide

A wafer of titanium dioxide (TiO2) typically refers to a thin slice or disc of the material, which is often used in various applications due to its unique properties. Titanium dioxide is a white, powdery substance that is known for its high refractive index, excellent opacity, and photocatalytic capabilities. Below are some common uses and characteristics of a titanium dioxide wafer:

1. **Properties**:

– **Chemical Formula**: TiO2

– **Color**: White

– **Crystalline Forms**: Rutile, anatase, and brookite are the most common crystalline phases of TiO2.

– **Melting Point**: Approximately 1,825 degrees Celsius (3,307 degrees Fahrenheit)

– **Hardness**: 5.5 – 6 on the Mohs scale

– **Stability**: It is stable and nontoxic under normal conditions.

2. **Applications**:

– **Photocatalysis**: TiO2 wafers can be used as a catalyst in the process of breaking down organic compounds and pollutants under ultraviolet light, which is useful in environmental cleanup and air purification.

– **Solar Cells**: TiO2 is used in dye-sensitized solar cells (DSSCs) as an electrode material due to its ability to absorb light and facilitate electron transfer.

– **Electronics**: As a semiconductor, TiO2 can be used in electronic devices, such as capacitors and transistors.

– **Coatings**: TiO2 is often used in paints and coatings to provide whiteness and opacity.

– **Medicine**: Due to its biocompatibility, TiO2 can be used in medical applications, such as in the development of orthopedic and dental implants.

3. **Production**:

– Titanium dioxide wafers are typically produced through processes such as sol-gel, emulsion, or hydrothermal synthesis, followed by calcination to achieve the desired crystalline phase and purity.

4. **Handling**:

– When handling titanium dioxide wafers, especially in its fine powder form, appropriate safety measures should be taken to avoid inhalation and skin contact, as it can cause respiratory irritation and skin sensitization in some individuals.

It’s important to note that the term “wafer” is more commonly associated with semiconductor materials like silicon, which are cut into thin slices for use in integrated circuits. When referring to titanium dioxide, “wafer” is not a standard term, and it might be more appropriate to refer to it as a “slice,” “disc,” or “film,” depending on its intended application and form.
