General description

Strontium hydroxideoctahydrate is a white crystalline substance that is commonly used in the production of ceramics, as a raw material for other strontium compounds, and as a chemical reagent. It is also used as a sol-gel precursor to fabricate Sr-based thin films for various catalytic and optoelectronic applications.

Application

Strontium hydroxide octahydrate can be used:
  • As a precursor to synthesize Sr-based nanomaterials by sol-gel hydrothermal method.
  • To fabricate perovskite solar cells with enhanced performance.
  • To synthesize solid base catalysts for solid-liquid interface reactions.
