Description

Sodium Tellurate is an inorganic salt of telluric acid, a key source of the tellurate anion (TeO42-). This compound is valued for its role as a stable and soluble tellurium source in advanced material synthesis and specialty chemical manufacturing. It is primarily utilized by industries involved in electronics, glass and ceramic production, and chemical research. Sodium Tellurate CAS NO 20730-46-5 is essential for processes requiring controlled oxidation states of tellurium.

Application

• Glass & Ceramics Manufacturing: Acts as a fining agent and colorant to produce specific optical properties and reduce bubbles.
• Electronics & Semiconductor Industry: Used in the synthesis of tellurium-containing thin films and thermoelectric materials.
• Chemical Synthesis & Catalysis: Serves as a precursor or oxidizing agent in organic and inorganic synthesis.
• Laboratory & Analytical Reagents: Employed as a standard or reagent in analytical chemistry and research.
• Specialty Alloys: Used in the production of alloys where tellurium imparts specific mechanical or corrosion-resistant properties.
• Battery Research: Investigated as a component in advanced battery systems and energy storage materials.
