Ferrotitanium powder is a processed form of titanium-bearing ferroalloy used to introduce titanium into molten steel or industrial alloy systems. Unlike lump ferrotitanium, powder form allows faster dissolution, improved reaction efficiency, and more precise control of alloy composition.
Particle size is one of the most critical parameters in FeTi powder selection because it directly affects melting behavior, reaction kinetics, and titanium recovery rate during steelmaking or metallurgical processes.

Why Particle Size Matters in Ferrotitanium Powder
The size of ferrotitanium powder determines how quickly it reacts in molten steel and how efficiently titanium is absorbed into the final alloy structure.
| Particle Size Effect |
Metallurgical Impact |
| Finer particles |
Faster dissolution and higher reaction efficiency |
| Coarser particles |
Slower reaction but better handling safety |
| Uniform size distribution |
Stable titanium recovery and consistent steel quality |
Steel manufacturers select particle size based on furnace type, alloying method, and required titanium addition speed.
Common Particle Size Ranges of Ferrotitanium Powder
Ferrotitanium powder is available in multiple standardized and customizable size ranges to meet different industrial applications.
| Particle Size |
Mesh Equivalent |
Main Application |
| 0–1 mm |
16–18 mesh |
General steelmaking and alloying |
| 1–3 mm |
6–16 mesh |
Controlled alloy addition in furnace operations |
| 3–10 mm |
2–6 mesh |
Slow-release titanium addition |
| 10–50 mm (granules) |

Bulk alloying and ladle addition |
These ranges are widely used in metallurgical industries, but customized sizing is often available depending on production requirements.
Fine Ferrotitanium Powder Grades
Fine ferrotitanium powder is commonly used in applications requiring rapid reaction and high dispersion efficiency.
| Fine Powder Range |
Typical Use |
| <100 mesh |
Welding electrodes, powder metallurgy |
| 100–200 mesh |
Special steel alloying, high-speed reaction systems |
| <325 mesh |
Advanced materials and research applications |
Finer powders provide faster titanium release but require careful handling due to oxidation sensitivity and dust control requirements.
Coarse Ferrotitanium Granules
Coarse granules are typically used when controlled, slow-release alloying is required in large-scale steel production.
Advantages include improved safety during handling, reduced oxidation risk, and better control in continuous steelmaking processes.
How Particle Size Affects Steelmaking Performance

In industrial practice, a balanced particle size distribution is often preferred to optimize both efficiency and stability.
Production of Ferrotitanium Powder
Ferrotitanium powder is produced through mechanical crushing, grinding, and screening of ferrotitanium ingots or blocks. Advanced processes include air classification and magnetic separation to ensure uniformity and remove impurities.
Some high-end applications use gas atomization or specialized milling to achieve ultra-fine particle sizes with controlled morphology.
Applications of Ferrotitanium Powder by Particle Size
Steelmaking Industry
Used for deoxidation, denitrification, and grain refinement. Particle size determines titanium dissolution rate in molten steel.
Welding Consumables
Fine powders are used in welding rods and flux-cored wires to improve arc stability and weld strength.
Powder Metallurgy
Ultra-fine FeTi powder is used in precision alloy components and advanced manufacturing processes.
Special Alloy Production
Controlled particle sizes ensure precise titanium addition in aerospace and high-performance alloy systems.
Choosing the Right Particle Size
Selecting the appropriate ferrotitanium powder size depends on:
- Steel grade requirements
- Furnace type (EAF, LF, induction furnace)
- Desired titanium dissolution speed
- Alloying method (ladle addition, in-furnace addition)
- Process safety requirements
In general, medium particle sizes (1–3 mm and 0–1 mm) are most widely used in industrial steelmaking due to their balance of performance and control.
FAQ About Ferrotitanium Powder Particle Size
What is the most common particle size of ferrotitanium powder?
The most commonly used particle sizes are 0–1 mm and 1–3 mm. These ranges provide a good balance between dissolution speed, titanium recovery efficiency, and operational safety in steelmaking processes.
Which particle size dissolves fastest in molten steel?
Finer powders, especially below 100 mesh, dissolve the fastest due to their larger surface area. However, they must be carefully controlled to avoid excessive reaction speed or oxidation losses.
Why are coarse ferrotitanium granules still used?
Coarse granules provide slower, more controlled titanium release, which is beneficial in large-scale steel production where stability and process control are more important than rapid reaction speed.
Can ferrotitanium powder size be customized?
Yes, manufacturers can customize particle size distribution according to customer requirements, including ultra-fine powders, standard industrial grades, and coarse granules for specific metallurgical applications.
Does particle size affect titanium recovery rate?
Yes, particle size significantly affects recovery. Finer particles may increase reaction efficiency but also increase oxidation risk, while coarser particles provide more stable but slower titanium absorption.
