Description

Barium Bis(Thioborate) CAS NO 27184-78-7 is an inorganic barium salt of thioboric acid, serving as a specialized chemical intermediate and additive. Its value lies in its ability to act as a source of both barium and sulfur/boron species in high-performance material synthesis and chemical processes. This compound is primarily needed by manufacturers in the lubricant, ceramic, and specialty glass industries, as well as by research institutions developing novel inorganic materials and catalysts.

Application

• As a high-temperature extreme pressure (EP) additive and friction modifier in advanced lubricating greases and solid lubricants.
• As a precursor or dopant in the production of specialty optical glasses and ceramics with modified refractive indices or thermal properties.
• As a sulfur and boron source in the synthesis of inorganic pigments and corrosion-inhibiting coatings.
• In research and development of novel solid-state electrolytes or battery materials due to its ionic conductivity potential.
• As a chemical intermediate for preparing other thioborate compounds and complexes used in catalysis.
• In the formulation of pyrotechnic compositions and ignition compounds where barium acts as a green colorant.

Quality Control

Our Barium Bis(Thioborate) is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including assay and impurity profiling, to meet agreed-upon specifications. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and potential degradation. Keep away from incompatible materials such as strong acids and oxidizers.
