🏺 Ceramic Sintering: Densification & Grain Growth (2D)

A cross-section companion to the 3D kiln scene: watch ceramic powder grains fuse at the necks and densify under real Arrhenius sintering kinetics, then watch grain coarsening quietly eat into the strength that densification just bought.

This 2D companion renders the kiln scene as a flat cross-section: a grid of ceramic powder grains, each a plain circle, fused by growing necks that thicken and lighten in color as the bed densifies. It runs the same solid-state sintering kinetics as the 3D original — an Arrhenius temperature dependence, a two-sphere neck-growth model, a cubic grain-growth law, and a combined Ryshkewitch/Hall-Petch strength prediction — so pushing the sintering temperature up still densifies the bed faster while coarsening the grains faster too, letting you watch the predicted strength number rise, plateau and then fall if you keep firing past it.

⚙ Under the hood

Neck growth follows (x/a)^5 ∝ k(T)·t/a³, relative density is derived from the neck ratio, grain diameter grows by a cubic law d³ = d0³ + Kg·k(T)·t, and predicted strength combines the Ryshkewitch porosity term exp(-b·P) with a Hall-Petch grain-size term √(d0/d) — all driven by the same Arrhenius rate k(T) as the 3D scene.
