On , the crystal—packed in a custom foam-lined container, escorted by two security officers—was loaded onto a Bhobaneswar–New Delhi Rajdhani Express train. The Tragedy (January 13, 2017) Near Kanpur, around 3:45 AM, the train hit a derelict tractor left on the tracks. Three coaches derailed. The security car was crushed.

Why did it form? The leading theory, published in Nature (1999, Vol. 398): a unique organic surfactant from the local bauxite (possibly from decomposed laterite vegetation) acted as a at the exact moment a tiny seed crystal began growing. Then, an unprecedented 18-hour period of laminar flow and steady supersaturation allowed the crystal to grow laterally, not in powders. It was a one-in-a-billion statistical fluke. nalco 8177

Here is the complete, detailed story of , the legendary alumina hydrate crystal that became an unexpected icon in the world of materials science and beyond. The Birth of a Crystal (1994) In the sprawling, steam-belching complex of the National Aluminium Company (NALCO) in Damanjodi, Odisha, India, production was routine. Hundreds of tons of alumina hydrate were precipitated daily from Bayer process liquors, destined to be calcined into smelter-grade alumina. On , the crystal—packed in a custom foam-lined

It turned up six months later in a , about to be melted down. A scrap dealer noticed its unusual clarity and contacted a geology professor at IISc. The thief? A contract electrician who thought it was “just a big piece of plastic or glass” and sold it for ₹500. The security car was crushed

When rescue workers reached the debris, they found the container . NALCO 8177 had broken into hundreds of jagged fragments , scattered across the gravel and twisted metal.

Recovery teams collected 98% of the mass, but the crystal was irreparably destroyed. No single piece larger than a thumbnail remained intact.
