FAQS on conductive graphite powder
Q: What are common applications of conductive graphite powder?
A: Conductive graphite powder is widely used in lithium-ion batteries, anti-static coatings, and electronic circuitry. Its high conductivity and thermal stability make it ideal for enhancing electrical performance in industrial and consumer products.
Q: How does conductive graphite sheet differ from powder?
A: Conductive graphite sheets provide flexible, uniform conductivity for EMI shielding or heat dissipation in devices like smartphones. Unlike powder, they offer pre-formed structures but lack the versatility for custom composite mixing.
Q: Why choose extra fine graphite powder?
A: Extra fine graphite powder has ultra-small particle sizes (1-10 microns), enabling smoother dispersion in resins or inks. This improves conductivity in precision applications like 3D printing or high-end sensors.
Q: Can conductive graphite powder replace metal in thermal management?
A: Yes, graphite powder efficiently dissipates heat in composites while being lighter than metals. It's preferred in lightweight electronics and EV components where weight reduction is critical.
Q: Is conductive graphite powder safe for wearable devices?
A: When properly encapsulated, it's safe due to non-toxicity and chemical inertness. However, direct skin contact with loose powder should be avoided to prevent irritation or contamination.
