Overview

Engineering reference data for Ceramics Properties in material science and properties.

Key Formulas

Stress

σ=FA\sigma = \frac{F}{A}

Force per unit area.

Strain

ε=ΔLL0\varepsilon = \frac{\Delta L}{L_0}

Change in length per original length.

Hooke's Law

σ=Eε\sigma = E \varepsilon

Stress proportional to strain in elastic region.

Thermal Expansion

ΔL=αL0ΔT\Delta L = \alpha L_0 \Delta T

Length change due to temperature.

Variables

Material Properties Table

Material Definitions

  • Porcelain: A ceramic material made by heating selected and refined materials, often including clay in the form of kaolinite, to high temperatures.
  • Cordierite: A crystalline magnesium aluminosilicate mineral.
  • Steatite: Also known as soapstone or soaprock. It is a metamorphic rock (a talc-schist) largely composed of the mineral talc and is rich in magnesium.
  • Forsterite (Mg₂SiO₄): The magnesium-rich end-member of the olivine solid-solution series.

Key Operating Temperatures

The Maximum Safe Operating Temperature is a critical design parameter. Materials like Alumina Silicate Refractory (up to 1700°C) and Alumina Porcelain (up to 1500°C) are suitable for high-temperature applications, whereas standard Porcelain is limited to ~400°C.
