摘要:
A metal composition comprising zinc oxide whiskers dispersed in a metal matrix. The whiskers comprise at least one needle crystal having a basal part whose diameter is from 0.7 to 14 micrometers and a length from the basal part to its tip of from 3 to 200 micrometers. The metal composition is isotropically reinforced with respect to mechanical strength and is significantly improved in free cuttability.
摘要:
Fluorescent materials comprising zinc oxide whiskers of a tetrapod form having a central body and needle crystal projections radially extending from the central body with or without additive elements capable of changing fluorescent characteristics and/or fluorescence color are described. The fluorescent materials may be a mixture of insulating fluorescent substance and the whiskers which are used mainly as a conductive material. These fluorescent materials are energized at low-speed electron beams and are capable of emitting fluorescence at low voltages.
摘要:
A conductive composition containing at least zinc oxide whiskers. The conductive composition an be used to provide a conductive resing composition and a conductive coating composition, which have various uses, particularly in conductive layers, conductive supports or protective layers of electrophotographic photosensitive members.
