Hafnium Carbide Powder Hfc

Changsha Langfeng Metallic Material Co., Ltd. supplies hafnium carbide powder (HfC) characterised by a molecular weight of 190.54 g mol⁻¹, density of 12.2 g cm⁻³ and an electrical resistivity of 1.09 × 10⁻⁶ Ω·cm. The material melts at approximately 3890 °C, softens between 1700 °C and 2500 °C and boils near 4603 °C, making it one of the most refractory binary carbides. It appears as a black, odourless powder, is insoluble in water and crystallises in a cubic lattice.

Typical commercial grades of hafnium carbide powder are supplied with purities above 99 % and particle sizes ranging from 1 to 10 µm, which supports consistent sintering behaviour. The product is noted for high surface activity, oxidation resistance and excellent heat‑preservation properties, traits valued in aerospace and nuclear material programmes. Standard industry practice calls for handling the powder in sealed, moisture‑proof containers to avoid contamination.

Primary users include manufacturers of hard‑alloy components, thermal‑spray coatings and ceramic matrix composites for rocket nozzles. Importers should confirm the batch purity certificate, packaging dimensions and the supplier’s accepted Incoterms before finalising a contract. Typical order packaging is in 25 kg sealed polyethylene bags, and freight forwarders often request a commercial invoice and material safety data sheet. Because response data show no recent replies, buyers are advised to request a test sample and verify lead‑time expectations directly with the supplier.

Changsha Langfeng Metallic Material Co., Ltd. is located at Tianxiong Road 98, Furong Area, Changsha, Hunan 410100, China. The supplier is classified as an imported tier with a harbor trust level, indicating that it meets basic verification criteria on the platform. Response statistics show a 0 % recent reply rate and no recorded response time, which suggests that buyers should proactively seek updated contact information before initiating negotiations.

The company’s product catalogue includes a range of powdered carbides such as chromium carbide, molybdenum carbide, niobium carbide and titanium carbide, all intended for processes like plasma spraying, thermal‑spray coating, additive manufacturing and powder metallurgy. The listing does not provide proprietary certifications, production capacities or pricing details, so interested importers should request those specifics directly from the supplier.
