How is China's potassium hydroxide capacity landscape shifting?

Watch the Qinghai capacity closely—it's tied to salt lake potassium resources and could shift cost curves if fully ramped. Also, Sanfu's 2026 Q1 net profit jumped 44% year-on-year, showing the KOH upcycle is still running. Buyers should secure annual contracts with integrated producers to avoid spot volatility.

What are the key energy-saving options in potassium hydroxide evaporation?

Energy costs are the second-largest variable after potassium chloride feedstock. With KCl prices volatile, evaporation efficiency directly impacts cash margins. Also, recovered condensate at 90°C+ can preheat feed, cutting thermal losses further—a low-capital tweak worth auditing before committing to full MVR.

Why is analytical grade potassium hydroxide only about 85% pure?

This also explains why electronic-grade KOH commands a premium. Producers use recrystallization and low-sodium feedstocks to reach 48% liquid grades with sodium below ppm levels. Buyers should verify whether the 85% balance is mainly water, carbonate, or sodium—each affects downstream use differently.

Overview

Potassium hydroxide (caustic potash, CAS 1310-58-3) is a white, strongly alkaline and corrosive solid with a density of 1.450 g/mL at 20°C, a melting point of 361°C, and a boiling point of 1320°C. It is a versatile strong base, more alkaline than sodium hydroxide, used across industrial, chemical, and electronic sectors.

Industrial: used in refining petroleum products and as a key reagent in numerous chemical syntheses.
Chemical synthesis: acts as a base in organic reactions, such as isomerizing terminal alkynes, though with lower efficiency than stronger bases like sodium amide.
Electronics: high-purity electronic-grade KOH (up to 99.999%) is used in semiconductor material processing.
Production: manufactured via electrolysis of potassium chloride solution, yielding KOH, chlorine, and hydrogen.

China's production landscape includes diaphragm-process and higher-purity grades, with analytical-grade KOH typically at ≥85% purity due to impurities like K₂CO₃ and sodium. The industry has seen capacity expansion and some sodium hydroxide units converted to KOH production, though overall capacity exceeds output, leading to low operating rates and structural oversupply.

Key domestic producers:
Sanfu Co. – expanded potassium-series capacity, including electronic-grade products.
Aladdin – supplier of high-purity electronic-grade KOH.
