Description

Strontium Hydroxide Octahydrate is a crystalline inorganic compound primarily valued for its strong basicity and role as a strontium source. This material is essential in applications requiring precise pH adjustment or the controlled introduction of strontium ions. It serves as a critical raw material for industries including specialty glass manufacturing, sugar refining, and lubricant greases, where its chemical properties are leveraged for process optimization and product formulation.

Application

• As a strontium precursor in the production of specialty glasses and ceramics, including cathode ray tubes (CRTs) and ferrite magnets.
• In the refining of beet sugar to precipitate non-sugars and improve crystallization efficiency.
• As a key component in the formulation of high-temperature lubricating greases, where it acts as a thickener.
• For the production of other strontium compounds, such as strontium carbonate and strrontium nitrate.
• In laboratory and research settings as a strong base for chemical synthesis and pH adjustment.
• In the treatment of wastewater for the removal of heavy metals through precipitation.
• As a drying agent for gases and solvents, leveraging its hygroscopic nature.

Quality Control

Our Strontium Hydroxide Octahydrate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, heavy metal screening, and loss on drying, to meet defined specifications. A Certificate of Analysis (COA) detailing these results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture and carbon dioxide, which can degrade product quality.
