品名 Item: MWNT, as-produced cathode deposit

货号 Catalog# MRMW

包装规格  1g；20g；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；20g；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.
