Al4C3 Aluminum Carbide Powder CAS 1299-86-1

Aluminum Carbide (Al₄C₃) is a highly reactive ceramic compound known for its extreme hardness, thermal stability (decomposes at ~2100°C), and unique chemical properties. This yellow-brown crystalline material is primarily used in advanced metallurgy, composite materials, and specialized chemical applications, offering a combination of lightweight properties and high-temperature performance.

Ultra-Hard: Comparable to boron carbide (B₄C) in abrasion resistance
Lightweight: Lower density than most technical ceramics
Reactive: Hydrolyzes to produce methane (CH₄) in controlled conditions
Thermal Stability: Maintains structure in inert atmospheres up to 2000°C
