Hevítésiporozitás
Hevítésiporozitás refers to a phenomenon observed in certain porous materials when subjected to heat. The term, originating from Hungarian, translates roughly to "heating porosity." It describes the increase in pore volume or the formation of new pores within a material due to thermal treatment. This process can occur in a variety of substances, including ceramics, refractories, and some metallic alloys, particularly those with organic binders or volatile components.
When a material containing pore-forming agents or trapped volatiles is heated, these substances can decompose or
