Pick two axes — watch the four families trade places
A representative family-level comparison on tiered bands (Low → Very high). Higher position never means “better overall” — it means better on that axis.

Teaching visualization on tiered bands (Low / Moderate / High / Very high) synthesized from the review literature for typical dense grades — not datasheet values and not design allowables. Real properties vary substantially with purity, stabilizer system, grain size, porosity, atmosphere, and processing route, and the families overlap; consult grade datasheets and fired test coupons for engineering numbers.
