The **chemical properties** of advanced inorganic materials are central to their performance in
catalysis, sensors, batteries, corrosion resistance, semiconductors, and other high-tech
applications. These properties describe how materials **react with other substances**, their
**stability**, and how they **change composition or structure** under various environments.

## 🧪 Key Chemical Properties of Advanced Inorganic Materials
| Property | Description |
| -------------------------------- | ------------------------------------------------------------------------------------------------- |
| **Chemical stability** | Resistance to decomposition, oxidation, or reaction in harsh
environments (heat, acid/base, etc.) |
| **Oxidation-reduction behavior** | Tendency to gain or lose electrons (important in redox
reactions and catalysis) |
| **Acid-base character** | Behavior as Lewis or Brønsted acid/base (especially in oxides
and catalysts) |
| **Thermal stability** | Resistance to decomposition or phase change at high
temperatures |
| **Corrosion resistance** | Resistance to degradation in air, moisture, or
chemicals |
| **Surface reactivity** | Chemical activity at surfaces or interfaces (important in catalysis,
sensors, and batteries) |
| **Chemical functionalization** | Ability to be modified with functional groups or dopants to
tune properties |

## ⚙️ Examples of Chemical Properties in Specific Advanced Inorganic Materials
### 1. **Transition Metal Oxides (e.g., TiO₂, CeO₂, MnO₂)**
* **Redox activity**: Can switch between multiple oxidation states (e.g., Ce³⁺/Ce⁴⁺), crucial for
catalysis and sensors.
* **Surface oxygen vacancies**: Increase chemical reactivity and catalytic activity.
* **Stable under**: Heat, UV, mild acids/bases.
* **Applications**: Catalysts, gas sensors, photocatalysis.

### 2. **Perovskites (e.g., CH₃NH₃PbI₃, BaTiO₃)**
* **Halide perovskites**:
* Chemically unstable in moisture, oxygen, heat → degrade over time.
* Highly reactive surfaces.
* **Oxide perovskites**:
* Chemically robust, stable at high temperatures.
* Exhibit proton/electron conduction, redox activity.
