<p>PURPOSE:To provide an electric resistance material which has a large specific resistance, high heat resistant properties, and a relatively small resistance- temperature coefficient. CONSTITUTION:2-25 atomic % zirconium is added to ternary alloy composed of 35-55 atomic % chromium, 2-23 atomic % aluminum and 37-58 atomic % boron to obtain quaternary alloy. Further, 15-25 atomic % oxygen is added to the quaternary alloy to obtain the electric resistance material.</p> |
