1891 — The Furnace Breakthrough

Edward G. Acheson accidentally synthesizes SiC while chasing artificial diamond, trademarks the abrasive Carborundum, and founds the Carborundum Company. Hydroelectric power at Niagara Falls soon scales production. (Cue the glow of 19th‑century megawatts.)

1893–1906 — Meteor Crater & Moissan

Henri Moissan identifies natural SiC (later named moissanite) in the Canyon Diablo meteorite. He wins the 1906 Nobel Prize in Chemistry (for isolating fluorine and the Moissan furnace), cementing his place in science lore.

1906–1927 — Radio & “Cold Light”

SiC becomes a rugged crystal detector in early radios; then H. J. Round (1907) observes electroluminescence from SiC, and Oleg Losev (1920s) builds pioneering SiC LEDs and imagines opto‑telecom decades early. Weak glow, huge idea.

1930s–1960s — Art & Abrasives

Carborundum grits reshape printmaking. WPA artists like Dox Thrash develop carborundum mezzotint, while studios experiment with “carborundum collagraph.” SiC also becomes synonymous with sandpaper and grinding wheels in workshops worldwide.

1980s–1990s — From LEDs to Wafers

SiC returns center‑stage in electronics: materials pioneers grow larger single crystals and wafers. Meanwhile, blue LEDs^1 arrive via GaN, but SiC underpins substrates and keeps advancing in power devices.

1998–Today — Jewelry & Power

Gem‑quality lab‑grown moissanite debuts, gaining a following for its fire and ethics‑first story. In parallel, 4H‑SiC devices roll into chargers, solar inverters, and EV drive units — the quiet cultural shift behind faster charging and longer road trips.

Carborundum: the Trademark that Stuck

“Carborundum” began as a protected brand for Acheson’s abrasive SiC and quickly became workshop shorthand for grit, whetstones, and grinding wheels. It’s one of those brand‑names‑turned‑household‑nouns (like “thermos” or “zipper”) — only this one can literally grind.

Radios & Early Semiconductors

Before vacuum tubes dominated, the carborundum detector helped ships and stations receive Morse code with fewer fiddly adjustments than delicate cat‑whisker crystals. A tough seed of semiconductor culture was planted long before the word “transistor” existed.

Electroluminescence: The Quiet Glow

Round’s 1907 note and Losev’s 1920s devices showed that crystals could glow under an electric push — a cultural pivot that feeds directly into today’s display‑everywhere world. Even if the first SiC lights were dim, they were philosophically blinding.

Carborundum Mezzotint

In the late 1930s, printmakers at the WPA’s Philadelphia workshop, including Dox Thrash, adapted carborundum abrasives to create lush, velvety tonal ranges. Later, Henri Goetz popularized “carborundum collagraph,” letting artists paint grit onto plates for painterly textures. SiC left the factory and walked into the studio.

A Joke that Became a Rallying Cry

“Illegitimi non carborundum” — mock‑Latin for “Don’t let the bastards grind you down” — riffs on the abrasive’s name. It resurfaced in pop culture (including The Handmaid’s Tale) as an emblem of resistance. Latin purists may wince; everyone else smiles and keeps going.

“Rainbow Carborundum”

Those iridescent, spiky plates in gift shops? Furnace‑grown SiC with thin oxide films that throw oil‑slick colors. They’re industrial by birth and exuberant by nature — delightful display pieces when described transparently.

Meteor Memory

“Star‑grain bright from ages old,
Furnace‑born and space‑cold gold;
Steady spark, my course align—
Will to work and heart to shine.”

Grind No More (A Carborundum Charm)

“Grit to gloss and rough to clear,
Guard my joy from wear and fear;
Let no ‘bastards’ grind me down—
I rise, refined, and wear my crown.”

(A wink at the famous mock‑Latin motto. May your mood stay un‑abraded.)
