General description
氢氧化钾是一种无机化合物，化学式为 KOH。它是一种强碱，通常被称为苛性钾。苛性钾主要用于制造钾盐、酸碱滴定和有机合成。此外，KOH 还可用作一些燃料电池和碱性电池的电解质。氢氧化钾容易与酸反应。它用于各种反应，如亲核反应、加成反应和碱性水解反应。此外，它还被用作醛型反应的催化剂。
Application
氢氧化钾可用于：
- 制备经 KOH 处理的粉状活性炭，作为化学气相沉积（CVD）法合成碳纳米管（CNT）的催化剂。
- 作为尿素分子内 N-芳基化中的碱，以形成苯并咪唑-2-酮。
- 作为催化剂，通过一锅、三组分（Meldrum 酸、芳基醛和 5,7-二羟基苯并吡酮衍生物）反应合成烷内酯类化合物（10-芳基取代-9,10-二氢吡喃[2,3-h]苯并吡酮-8-酮）。

We demonstrate a novel technique to fabricate sub-micron silicon nitride waveguides using conventional contact lithography with MEMS-grade photomasks. Potassium hydroxide anisotropic etching of silicon facilitates line reduction and roughness smoothing and is key to the technique. The fabricated waveguides is
