Which of the following does an increase in porosity in a ceramic NOT result in?

An increase in porosity in a ceramic material is generally associated with several predictable changes in its properties. When porosity increases, the material's ability to support loads effectively decreases, primarily due to the reduction in the effective cross-sectional area that can bear stress. This weakening is often manifested in diminished mechanical properties such as strength and stiffness.

One of the significant consequences of increased porosity is the enlargement of the surface area available for biological interactions, which can promote bone ingrowth and enhance the integration of the ceramic with the surrounding tissue. Thus, a more porous ceramic can facilitate better bone integration due to the higher surface area and interconnected pores that permit cellular infiltration.

The correct choice indicates that increased porosity does not enhance load-bearing capabilities. In fact, this property typically deteriorates because the structural integrity of the ceramic is compromised as more void spaces are created. Therefore, the increase in porosity primarily leads to reduced mechanical strength and load-bearing ability, rather than improved performance in these areas.
