MulliteDigitalfire
Notes. Mullite is a mineral of long interlocking needle-like crystal structure that is very resistant to thermal shock failure (has a low thermal expansion).It is also has a low thermal conductivity and is very refractory thus the theoretical formula (of 71.8 alumina and 28.2 silica) bears little resemblance to the real world material (we have provided a typical non-theoretical analysis).
