Graphite is used as lubricant.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Structure of Graphite:**
- Graphite has a unique layered structure composed of hexagonal rings of carbon atoms. Each layer consists of carbon atoms arranged in a two-dimensional plane.

2. **Hybridization of Carbon in Graphite:**
- The carbon atoms in graphite are sp² hybridized. This means each carbon atom forms three sigma bonds with neighboring carbon atoms, creating a planar structure. The fourth electron is involved in a delocalized π-bonding system.
