समीक्षा

Engineered porosity plays an important role in achieving low thermal conductivity and hence on insulating performance. However, the loss of strength becomes an important disadvantage with increasing porosity. Quantity of porosity along with the tailored pore size becomes critical to choose an optimum as these properties conflicts each other. Methodologies are successfully developed to fabricate zirconia ceramics with optimum porosity and strength for thermal management applications.
