Molybdenum Briquette
Molybdenum Briquettes are a highly dense, compacted form of Molybdenum Oxide or Molybdenum concentrate, primarily used as an efficient alloying agent. They provide a precise and clean way to introduce Molybdenum into molten steel or iron.
Molybdenum is essential for enhancing the strength, hardness, weldability, and corrosion resistance of alloys, particularly at high temperatures. The briquette form ensures maximum metallurgical yield and minimal dust and handling loss.
Main Function and Characteristics
The primary function is to serve as a cost-effective and dense Molybdenum source. Molybdenum is a powerful alloying element that forms stable carbides, resulting in deep-hardening properties.
| Characteristic | Value Range | Primary Metallurgical Function |
|---|---|---|
| Molybdenum (Mo) Content | 55% to 65% | Defines the alloying strength and dosage required in the melt |
| Shape | Compacted Briquette | High density ensures deep penetration and high recovery rates in the melt |
| Melting Point | ~2623°C | Extremely high; requires high heat furnaces for dissolution (e.g., electric arc furnace) |
Classification

Molybdenum Briquette
1. Composition and Form Factor
Molybdenum Briquettes are manufactured by finely grinding and blending Molybdenum-bearing materials (often high-grade Molybdenum Oxide or concentrate) with a binder, then subjecting the mixture to high-pressure compaction.
- High Yield and Density: The briquette form is preferred over loose powder or ore because its high density minimizes oxidation and dust during handling. This results in a superior metallurgical recovery rate (yield) when charged into the furnace, ensuring that nearly all the Molybdenum content is successfully incorporated into the final alloy.
- Controlled Chemistry: Briquettes provide a precise unit of weight for alloy addition, which is crucial for producing specialty steels that require tight tolerance on their chemical composition.
2. Alloying Functionality
Molybdenum is a crucial alloying element for high-performance steels, primarily due to its impact on the microstructure:
- Strength and Hardness: Molybdenum is a potent carbide former. These fine, stable carbides increase the steel’s hardness and strength. It also promotes the formation of bainite and martensite during cooling, increasing the hardenability (the ability to harden deeper into the material).
- High-Temperature Performance (Creep Resistance): Molybdenum stabilizes the steel’s microstructure at elevated temperatures. This resistance to deformation over time (creep) is vital for hot-work tool steels and structural components operating near furnaces or engines.
- Corrosion Resistance: The addition of Molybdenum is key for austenitic and ferritic stainless steels (e.g., 316L). It enhances the passive chromium oxide layer, dramatically improving the steel’s resistance to localized pitting and crevice corrosion, especially in chloride environments (like seawater).
3. Applications
- Tool Steels: Used for punches, dies, and cutting tools that require high wear resistance and strength retention at high operating temperatures
- Pipeline and Structural Steels (HSLA): Molybdenum enhances the tensile strength and toughness of steels used in pipelines, bridges, and offshore structures
- Chemical Processing: Essential for alloys used in corrosive chemical reactors, pulp and paper equipment, and desalination plants
- Cast Iron: Improves the strength, toughness, and wear resistance of high-performance cast iron components

❓ 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. |

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. |
