What is TiH₂ Powder?
Titanium Hydride powder is a compound formed by combining titanium and hydrogen at specific high temperatures. This powder has unique characteristics that make it ideal for various applications, particularly in the metal powder industry. It’s widely used in areas like powder metallurgy, additive manufacturing, and even pyrotechnics. TiH₂ powder decomposes to titanium and hydrogen when heated, providing a convenient way to introduce titanium into processes where reducing oxygen or nitrogen contamination is critical.
Let’s dig deeper into the nitty-gritty details of TiH₂ powder and how it stacks up against other materials in terms of performance, versatility, and cost.
Composition of TiH₂ Powder
The chemical composition of TiH₂ powder is fairly simple: it’s composed of titanium (Ti) and hydrogen (H₂). What’s fascinating about TiH₂ powder is how these elements combine to give it properties that are distinct from pure titanium or other titanium compounds.
| 구성 요소 | 백분율 |
|---|---|
| 티타늄(Ti) | 95-99% |
| Hydrogen (H₂) | 0.7-4.5% |
| Oxygen (O₂) | <0.2% |
| Nitrogen (N₂) | Trace |
| 철(Fe) | Trace |
The high titanium content ensures that the material retains most of the desired characteristics of titanium—such as high strength and corrosion resistance—while the hydrogen content offers flexibility in metallurgical processes. The trace amounts of oxygen, nitrogen, and iron are carefully controlled to avoid compromising the overall performance of the powder.

Characteristics of TiH₂ Powder
1. Reactivity
TiH₂ powder is highly reactive, especially when exposed to high temperatures. When heated, the powder decomposes, releasing hydrogen and leaving behind pure titanium. This decomposition makes it incredibly useful in applications that require controlled atmospheres or reduced oxygen contamination.
2. Compressibility
One of the key advantages of TiH₂ powder is its excellent compressibility. This feature allows for easy forming into shapes, making it an ideal choice for powder metallurgy and metal injection molding.

The particle size of TiH₂ powder can vary depending on the specific grade or model. Fine particle sizes are better suited for additive manufacturing and coatings, while coarser powders are preferred for metallurgical applications.
4. Stability
Despite its reactivity, TiH₂ powder is relatively stable at room temperature. It can be safely stored and transported without the risk of spontaneous combustion or degradation, provided it is kept in dry conditions.
5. Porosity
Many grades of TiH₂ powder exhibit high porosity, making them well-suited for hydrogen storage and other applications that require gas absorption.
6. Density
The density of TiH₂ powder typically ranges from 2.7 g/cm³ to 4.5 g/cm³ depending on the grade. Higher-density powders are generally used for heavy-duty metallurgical applications, while lower-density options are preferred in lightweight composite materials.
