ABSTRACT:
Whiskers of zinc oxide whose crystal structure includes a central body and four needle crystal projections radially extending from said central body are described. The whiskers are so unique a structure that they are applicable to various materials such as metals, resins, ceramics and the like as a reinforcing material. The whiskers may be in the form of a mixture of whiskers of zinc oxide having crystal structures including two, three, four and/or five needle crystal projections. A method for preparing such whiskers is also described.
