What Are You Looking For?
Standard off-the-shelf boron materials rarely satisfy the rigorous demands of high-end manufacturing. BoronHub delivers full-spectrum customization covering chemical purity, isotopic abundance, particle size and morphology from atomic scale to macroscopic granules, eliminating the need for you to compromise on process design due to substandard generic materials.
I. Chemical Purity Customization
| Grade | Purity | Total Metallic Impurities | Typical Applications |
| 2N | 99% | ≤ 10,000 ppm | Metallurgical additives, refractory materials |
| 3N | 99.9% | ≤ 1,000 ppm | Fine chemicals, precursor for boride synthesis |
| 4N | 99.99% | ≤ 100 ppm | High-performance ceramics, special alloys |
| 5N | 99.999% | ≤ 10 ppm | Semiconductor research, premium electronic packaging |
| 6N | 99.9999% | < 1.0 ppm | Doping for advanced-node chips, SiC power devices |
Metallic impurities of all grades are independently tested and verified by accredited third-party laboratories via ICP-MS or GDMS to ensure objective and traceable test data.
II. Isotopic Abundance Customization
Boron possesses two stable isotopes: ¹⁰B and ¹¹B, with natural abundances of approximately 19.8% and 80.2% respectively. The two isotopes exhibit vastly divergent nuclear properties, and customers’ abundance requirements vary by application scenario.
BoronHub supplies natural-abundance ¹⁰B/¹¹B product series as well as enriched ¹¹B series with adjustable isotopic ratios upon request, covering multiple chemical forms including elemental boron, boric acid and boron trifluoride. Isotopic abundance is precisely quantified by third-party institutions using ICP-MS or TIMS.
ℹ️ Note: Products enriched with ¹⁰B are subject to export control. Please consult our sales representatives for relevant inquiries.
III. Particle Size Customization
| Form | Adjustable Particle Size Range | Standard Available Grades | Application Scenarios |
| Powder | D50: 5 μm – 200 μm | Customized per client requirements | Fine chemicals, catalyst carriers, powder metallurgy |
| Granule | 500 μm – 10 mm | 1–10 mm (standard grade) | Metallurgical additives, alloy smelting |
Key controlled parameters: Full particle size distribution (D10 / D50 / D90) is precisely regulated with D50 deviation ≤ 1% to guarantee consistent performance across batches.
⚠️ Compliance Notice: For elemental boron products with purity exceeding 97%, only granular forms above 500 μm are available for export.
IV. Particle Morphology Customization
| Morphology Type | Characteristics | Typical Applications |
| Spherical / Near-spherical | Excellent flowability, high packing density | Powder metallurgy, raw material for additive manufacturing (3D printing) |
| Flaky | Large specific surface area, superior orientation performance | Thermal conductive fillers, lubricating coatings |
| Irregular lump | Sharp edges, strong mechanical interlocking | Superhard abrasives, thermal spraying |
| Regular crystalline block | Intact crystal facets, high mechanical strength | Semiconductor doping sources, synthesis of superhard materials |
Adjustable morphological parameters: Sphericity, BET specific surface area, integrity of crystal facets.
