Conductive Silicon Carbide [Carborundum]

Click For Summary
SUMMARY

The discussion centers on the creation of conductive Silicon Carbide (SiC) heating elements, referencing US patent 650234, which outlines a method for making carborundum articles by sintering crushed SiC crystals with 15-20% graphite for enhanced conductivity. The inquiry specifically addresses whether this historical process remains applicable for modern SiC heater elements, particularly when sintering at 2000°C. The discussion also seeks recommendations for sintering aids to optimize the process.

I am trying to create a conductive Silicon Carbide (SiC) heating element.

The US patent 650234 "Process of making carborundum articles", filed in 1899 states essentially that crushed SiC crystals can be be glued together (using diluted glue) then sintered. It states that the addition of 15-20% graphite is added when conductivity is desired.

Is this the same process used to create SiC heater elements today? In other words, if I sinter a quantity of SiC crystals with 20% graphite added, then sinter at 2000C, can I expect to be able to use the resulting SiC as a resistive heater element? Any recommended sintering aids?
