Abstract
A high temperature electrical resistance heater in which an electrically resistive strip is supported so that the strip may freely expand and contract and substantially all of the strip may directly radiate to provide maximum heat transport therefrom. The strip is carried in a serpentine configuration by support blocks which are arranged in abutting relation in spaced, parallel rows. Each block includes a lower portion embedded in a ceramic base and an upper portion extending above the base. The upper portion includes a structural portion which encircles minor portions of the strip to carry it spaced above the base to allow substantially unimpeded radiation from the strip and free strip expansion. Anchors securely hold the support blocks embedded within the base.
