Optimisation of toroidal ZTA anvils and gaskets; towards improved load and pressure performance

We have modified zirconia-toughened alumina anvil geometry and systematically varied single-toroidal, encapsulated, Ti–Zr gasket dimensions, exploring the resulting effects on pressure maximum load performance, which been measured using a Paris–Edinburgh press. Reducing curvature depth of recess at rear appears to permit repeated use anvils higher loads, general trend indicates that thinner gaskets may achieve pressures than thicker alternatives.
