Pite Klasifikasyon & Sètifikasyon nan gwo pite Tantal Crucible

 

Yon crucible Tantal pite segondè defini pa pite Pi gran pase oswa egal a 99.99%, elimine kontaminan tras pou satisfè demand sevè nan pwosesis materyèl ultra-sansib.

 

Nivo pite yo enkli 99.95% (klas komèsyal), 99.98% (klas analyse), ak 99.99% (klas elektwonik / nikleyè). Sètifikasyon atravè GDMS (glow discharge mas spectrometry) oswa ICP-MS (inductively coupled plasma mass spectrometry) verifye nivo enpurte yo: pa egzanp, 99.99% crucibles gen Fe mwens pase oswa egal a 5 ppm, Ni mwens pase oswa egal a 3 ppm, C mwens pase oswa egal a 10 ppm. Trasabilite sa a enpòtan anpil pou aplikasyon ayewospasyal (superalliaj k ap fonn) oswa semi-kondiktè (pwosesis segondè -k dielectrics).

Defi fabrikasyon gwo pite Tantal Crucible

Reyalize 99.99% pite mande pou pirifye avanse:
Zòn Raffinage: Yon zòn fonn travèse yon baton Tantal, konsantre enpurte nan yon bout (99.999% ka reyalize apre 10+ pase).
Fwad Crucible Endiksyon k ap fonn: Fonn Tantal nan yon kreze kòb kwiv mete dlo-refwadi, sa ki anpeche kreze-materyèl entèraksyon ak prezève pite.

Post-fabrikasyon, recuit vakyòm (1500 degre, 10⁻⁵ Pa) retire gaz absòbe, plis ranfòse pite.

 

Avantaj pèfòmans nan aplikasyon kritik

Nan epitaksi semi-conducteurs, 99.99% crucibles anpeche kontaminasyon dopant (egzanp, Fe chanje pwopriyete elektrik Silisyòm). Pou gaz nikleyè, yo gen fonn oksid iranyòm san yo pa entwodwi enpurte ki absòbe netwon -(pa egzanp, B, Cd). Pousantaj degasaj ki ba yo (<10⁻⁹ Torr·L/s·cm²) also suits ultra-high-vacuum (UHV) systems, unlike lower-purity crucibles that release volatiles.
