Abstract
Provided is a method for producing a silicon carbide ceramic easily and simply producing a silicon carbide ceramic having a small amount in resistivity change due to temperature change and being capable of generating heat by current application; and having a forming raw material preparing step of mixing two or more kinds of silicon carbide ceramic powders containing 4H—SiC silicon carbide crystals at respectively different content ratio to prepare a forming raw material; a forming step of forming the forming raw material into a formed body; and a firing step of firing the formed body to produce a silicon carbide ceramic being adjusted at a content ratio of 4H—SiC silicon carbide crystal to a desired value.
