摘要： The invention provides spacers for separating and supporting a faceplate structure and a backplate structure in a flat panel display, and methods for fabricating these spacers. Each spacer is typically made of ceramic, such as alumina, containing transition metal oxide, such as titania, chromia or iron oxide. Each spacer can be fabricated with an electrically insulating core and electrically resistive skins. The insulating core can be a wafer formed of ceramic such as alumina, and the resistive skins can be formed by laminating electrically resistive wafers, formed from alumina containing transition metal oxide, to the outside surfaces of the insulating core. Each spacer can also have a core of electrically insulating ceramic composition made of a ceramic containing a transition metal oxide in its higher oxide states, and electrically resistive outside surfaces made of a ceramic containing a transition metal oxide in lower oxide states. Face and/or edge metallization strips can optionally be provided on each spacer.
