WebJun 29, 2024 · Colorless CVD is reliably Type IIa, so it's identified that way on reports. Colorless HPHT are widely Type IIa but, depending on process, can have slight traces of boron. To account for this, confirmation of Type II, without stipulating a or b, is the default for colorless HPHT on reports.
