Working with Pyroceram 9606 CERAMMED
Is Pyroceram 9606 easy to machine?
After ceramming only diamond grinding, lapping, ultrasonic or laser machining works; do rough shaping in the parent-glass state and allow ~1–2 % crystallization shrinkage.
Can Pyroceram 9606 be welded?
Not weldable; join by glass frit sealing, active-metal brazing or ceramic adhesives, matching CTE (~4.5 ppm/K) to avoid seal stress.
Can Pyroceram 9606 be formed, bent or molded?
Formed as a glass — pressed, spun, cast or drawn — then given a two-stage nucleation/crystal-growth heat treatment near 1100–1250 °C.
What surface finishes work on Pyroceram 9606?
Fine grinding and polishing raise strength by removing surface flaws; can be metallized (Mo-Mn or thin-film) for substrate and RF applications.
Pyroceram 9606 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| SiO2network former | 54 – 58 | 56 |
| Al2O3 | 18 – 22 | 20 |
| MgOforms cordierite phase | 13 – 16 | 15 |
| TiO2nucleating agent | 7 – 10 | 9 |
