Question

why amorphous ceramics have low thermal conductivity​

Answer 1

Answer:

Umklapp scattering is the dominant process for thermal conductivity at high temperatures for low defect crystals. For amorphous ceramic materials, the mean free path may be considered approximately constant and, when temperature increases, thermal conductivity increases in proportion to the specific heat.
