Thermal expansion of silicon carbide materials

The influence of porosity and sintering additives on the thermal expansion of silicon carbide ceramics with additions of Al₂O₃, B(B₄C), and BeO is investigated in the temperature range 50–700°C.Notation thermal expansion coefficient - b constant in the exponent - n porosity - T temperature Daghestan State University, Makhach-Kala.
