The carbon nanotube is produced by vapor phase method，Depended on different from processor controlling carbon grown that will be different to diameter and length。The Vapor Grown Graphite Tube( VGGT) must be graphitized by super high temperature and physical treated specially to handle easily。
There are superior in thermal conductivity；electrical conductivity；lubricity；resilience；adsorptive capability and strength，so VGGT has many applications。
