# Industrial Specification: High-Purity Ferrotitanium Master Alloy

## 1. Technical Definition
High-purity iron-titanium alloy for steel and aluminum refinement

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Titanium content: 68-72 wt%, Iron content: 28-32 wt%, Impurity oxygen: &lt;0.15 wt%, Impurity nitrogen: &lt;0.05 wt%, Melting point: 1668-1685°C, Density: 4.51-4.55 g/cm³**. Failure boundary: **Oxygen content exceeding 0.20 wt% causes brittle titanium oxide formation, Nitrogen content exceeding 0.08 wt% creates titanium nitride inclusions, Titanium content below 65 wt% loses grain refinement effectiveness**, Mechanism: **Interstitial oxygen and nitrogen atoms occupy octahedral sites in titanium's HCP lattice, causing lattice distortion and embrittlement through Ti-O/Ti-N compound precipitation at grain boundaries during solidification**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

- **Caution**: 

### Q: What are the main applications of high-purity ferrotitanium master alloy?
**A**: This master alloy is primarily used in steelmaking and aluminum production for deoxidation, grain refinement, and improving mechanical properties through precise titanium addition.

### Q: How does the aluminum content affect the alloy's performance?
**A**: The trace aluminum content helps improve fluidity during melting and enhances deoxidation capabilities, while maintaining the high purity required for sensitive metallurgical processes.

### Q: What specifications are critical for industrial use of ferrotitanium master alloy?
**A**: Key specifications include titanium content (typically 30-70%), carbon content (kept low for purity), particle size (for controlled dissolution), melting point (for process compatibility), and bulk density (for handling and dosing).
