Temperature dependence of bulk resistivity of composites. (a) Dependence of TCR on temperature for soda-lime glass/30–70 vol% disk-like Ni-Cr alloy particle composites, compared with that for SUS304, a special cast iron, INCOLOY 800, and a commercial Ni-Cr alloy. (b) Change in the bulk resistivity with increasing temperature for soda-lime glass/30–70% disk-like Ni-Cr alloy particle composites, compared with commercial Ni-Cr alloys and SiC ceramics.
