Titanium Sponge Ingot
Titanium Sponge Ingot is the porous, elemental form of titanium created during the Kroll process, while Titanium Ingot is the solid mass resulting from the vacuum melting of this sponge. Together, they represent the primary feedstock for the entire titanium value chain.
As a raw material, Titanium Sponge is critical for the production of titanium mill products, powders, and as a high-value additive for steel and aluminum alloying.
Main Function and Characteristics
The primary advantage of Titanium is its exceptional Strength-to-Weight Ratio and Corrosion Resistance. Sponge serves as the pure chemical base, while Ingot serves as the structural starting point for forging, rolling, and milling.
| Characteristic | Value Range | Primary Metallurgical Function |
|---|---|---|
| Purity (Ti) | 99.5% to 99.8% | Determines the grade (Commercial Pure vs. Alloy base) |
| Density | ~4.50 g/cm³ | Roughly 60% of the density of steel |
| Melting Point | ~1668°C | High melting temperature requires vacuum processing |
Classification
- Metallurgy Focus: Transition Metal
- Primary Application Focus: Kroll Process Output (Sponge) / VAR Melt (Ingot) → Aerospace, Chemical Processing, and Steel Alloying
Key Performance Metrics
- Corrosion Resistance: OUTSTANDING — Formation of a stable, passive oxide film makes it immune to seawater
- Strength-to-Weight: SUPERIOR — The highest strength-to-density ratio of any metallic element
- Biocompatibility: EXCELLENT — Non-toxic and non-magnetic, essential for medical applications
Titanium Sponge Ingot
1. The Production Cycle (Kroll Process to Vacuum Arc Remelting)
Titanium does not occur freely in nature; it must be extracted from ores (Rutile or Ilmenite) through a complex multi-stage metallurgical process:
- Titanium Sponge (The Precursor): Produced by reducing Titanium Tetrachloride with molten Magnesium in a batch reactor known as the Kroll Process. The resulting metal is porous and sponge-like in texture. This “sponge” is crushed and serves as the raw material for melting or as an additive in steel production (to produce Ferro-Titanium).
- Titanium Ingot (The Consolidated Metal): To become useful structural metal, the sponge is compressed, welded into an electrode, and melted in a Vacuum Arc Remelting (VAR) or Electron Beam (EB) furnace. This process removes volatile impurities and creates a solid, homogenous cylinder (Ingot) ready for forging or rolling.
2. Applications
-
- Aerospace & Defense: The primary market for ingots, used to forge turbine blades, airframes, and landing gear requiring high strength
- Industrial & Chemical: Ingots are rolled into plates and tubes for heat exchangers and desalination plants due to immunity to chloride corrosion
- Steelmaking Additive: Titanium sponge is used as a direct addition or to manufacture Ferro-Titanium for deoxidation, denitrification, and grain refinement in high-quality steels
- Medical: High-purity ingots are the basis for biocompatible implants (joint replacements, dental implants)

❓ Frequently Asked Questions (FAQ)
Question | Elaborated Answer |
Q: What is the Refractoriness Under Load (RUL) of your refractories? | A: Refractoriness Under Load (RUL) is a critical property that defines the maximum temperature our materials can withstand while under compressive stress before deforming (softening). Since we offer a wide range of materials—from Alumina-Silicate Bricks to high-performance Silicon Carbide Bricks—the RUL varies significantly. For specific product data, please refer to the product data sheet or submit a quote request for the material you are interested in. |
Q: Where are the Rabatec refractories and materials produced? | A: Our products are primarily sourced from specialized manufacturing plants in China. Crucially, these facilities have all undergone rigorous audits and achieved comprehensive ISO certifications (Quality, Environment, and Safety), ensuring that production adheres to the highest global standards for consistency and performance. |
Q: What refractory materials does the company offer? | A: We supply a comprehensive portfolio of advanced refractory solutions, including: Shaped Products: Alumina & Silica Bricks, Basic & Specialized Bricks (e.g., Magnesia), SiC & Structural Ceramics, and Precast Shapes. Monolithic Products: Refractory Castables, Mixes & Mortars. Insulation: Insulation Fibre and High-Performance Insulation Products. |
Q: How should I choose the appropriate refractory material for my application? | A: Selecting the correct refractory is paramount to process efficiency. The choice depends on three key factors: 1. Operating Environment: Maximum process temperature and thermal cycling (shock). 2. Chemical Attack: Type of slag, molten metal, or corrosive gas being handled (acidic, neutral, or basic). 3. Mechanical Stress: Abrasion, erosion, and static load requirements. We recommend utilizing our detailed refractory solutions service to consult with our engineers for an optimized, application-specific recommendation. |
Q: Which monolithic material should I choose when patching an existing lining? | A: For patching and minor repairs, the ideal monolithic material depends on the parent lining material, the patching depth, and the need for a rapid return to service. Common choices include: Refractory Mortars & Mixes (for minor joints/surfaces) or Plastic Refractories (for areas requiring physical compaction). Always choose a patch material chemically compatible with the existing lining to ensure proper bonding and service life. |
Q: Can I receive product samples before placing a major order? | A: Yes. We gladly provide product samples for your internal testing and validation purposes. This ensures you can confirm the quality, composition, and fit of the material—such as our Refractory Castables or Alumina-Silicate Bricks—in your specific operational environment before committing to a bulk purchase. |
