    2013-10-1 · If small enough, zirconia rods exhibit shape memory and superelastic properties without crumbling. (Credit: Schuh; MIT.) Zirconia, one of the workhorses of the ceramic stable, has a well-known flaw—the crystallographic transition at about 1,150˚C from tetragonal to monoclinic structure involves a large volume change, and the accompanying strains can leave you with a pile of dust instead of ...

  • Ceramic Vs. Zirconia Sanding Belts: Which Is Better?

    2020-3-13 · The micro-grain structure of ceramic sanding belts results in smaller fragments being broken away during the grinding process, which gives them a longer performance life than their zirconia counterparts. However, unlike zirconia, ceramic is especially sensitive to pressure and heat, so their use in such applications must be carefully engineered.
