品名Item: MWNT, as-produced cathode deposit

货号Catalog# MRMW

包装规格1g：�/span>20g：�/span>150g

Description: Arc-produced cathode deposit with approximately 1 cm diameter and maximum of about 15 cm length. The cathode deposit has a hard, gray fused carbon shell that is made up of graphitic and diamond-like carbon. The core is a black fibrous material with 30-40 wt% multi-wall carbon nanotube content. The core is about 25 wt% of the cathode deposit. The product is over 99% carbon and is produced without catalysts. Nanotubes have 8-30 graphene layers, are 6-20 nm in diameter and 1-5 microns in length.

品名Item: MWNT, powdered cathode deposit core material,<53 micron particle size

货号Catalog# MRGC

包装规格1g：�/span>20g：�/span>150g

Description: Arc-produced MWNT with 30-40 wt% nanotube content. The product is removed from the cathode deposit and ground and sieved to -270 mesh size (<53 um). Impurities are multi-layer polygonal structures ("Buckyonions") and graphitic particles. Product is over 99% carbon and is produced without catalysts. Nanotubes have 8-30 graphene (graphite) layers, are 6-20 nm in diameter and 1-5 microns in length. Powder density is around 0.7 g/cc.
