Description of Tellurium dioxide:
Marketed under CAS 7446-07-3, Tellurium dioxide (chemical formula: TeO₂, molecular weight: 159.60) presents as a dense, white crystalline powder. It features a solid density of 5.67 g/mL and transitions to a liquid phase at a melting point of 733°C. While water-insoluble, it readily clears into solution when exposed to strong acids or alkalis. Structurally, this compound transitions between two polymorphic variants: tetragonal α-TeO₂ and orthorhombic β-TeO₂. In material science, it is highly valued as a conditional glass former, meaning it yields stable glassy networks when doped with minor fractions of secondary oxides or halides.
Where is it Used?
Advanced Photonics & Optics:
Due to its exceptional acousto-optic figure of merit, Tellurium dioxide serves as the core medium in acousto-optic modulators (AOMs) and deflectors used for precision laser etching, spectral analysis, and infrared sensing.
Specialized Glass & Fiber Tech:
The material is a staple in formulating high-refractive-index tellurite glasses. These matrices exhibit excellent mid-IR transparency, making them vital for pulling optical fibers and fabricating planar waveguides.
Solid-State Electronics:
Acting as a wide-bandgap semiconducting oxide with high carrier mobility, it integrates into next-generation photovoltaic cells and sensor layouts.
Chemical Precursor:
Industrial labs use it as a foundational feed material to synthesize II-VI compound semiconductors, thermoelectric alloys, and fine infrared crystalline structures.

Tellurium dioxide 's supply advantage and supply capability
Mill-Spec Quality Controls
Our standard commercial grade starts at a minimum purity of 99%. To streamline your vendor onboarding, each shipment arrives with an exhaustive Certificate of Analysis (COA). We map out more than just raw assay percentages—our quality reports track exact melting points, grain mesh distributions, and full trace metal profiles.
Centralized Spot Stocking
We keep our regional transit hubs fully stocked to eliminate lead-time anxiety. Our baseline packaging lineup covers 100g, 500g, and 1kg configurations. While small pilot-scale orders clear our dock within 24 to 48 hours, major commercial volumes are palletized and dispatched within 5 to 7 business days. Custom repacking is always available upon request.
Scalable Lot Sizes
We understand that procurement needs change between the lab bench and the factory floor. Our sales desk accommodates small R&D requirements (starting at 100g) just as easily as multi-ton industrial contracts. For mixed-product orders, we happily arrange LCL (Less than Container Load) logistics to optimize your freight costs.
Direct-from-Source Pricing
By sourcing directly from our domestic manufacturing infrastructure in China, we bypass the premium markups of trading brokers. This lean supply chain allows us to offer aggressive, high-volume pricing that protects your bottom line on bulk Tellurium dioxide contracts.
Regulatory Paperwork & Compliance
We keep your compliance department happy by bundling every delivery with up-to-date, multi-language MSDS sheets, technical data profiles, and official ISO-certification credentials. You get clear, verifiable proof of bulk density and purity before the material even enters your facility.
The packaging of Tellurium dioxide
We will use different standard packaging according to the product form.
● Liquid product: packaged in blue plastic drums, with a standard specification of 200 kg/drum; 220kg/barrel/250kg/barrel, tightly sealed barrel mouth, leak proof, resistant to bumps, suitable for long-distance transportation.
● Powdered products: packaged in thick cardboard drums, with a standard net weight of 25 kilograms per drum; 200 kg/barrel; 220kg/barrel/250kg/barrel, the barrel body is sturdy and pressure resistant, while also having good moisture resistance.
● Sample: sealed uniformly in aluminum foil bags with strong sealing abilities, which can prevent moisture and air from entering the bag and cause it to deteriorate.
Packaging can be tailored to meet customer needs, with standard packaging processes that ensure the quality of goods is maintained during storage and transport.

FAQ:
It is primarily utilized for its acousto-optic traits in laser control hardware, and as a base component for mid-IR tellurite glass formulations. Additionally, it is a crucial chemical precursor for growing thermoelectric crystals and II-VI semiconductors.
Absolutely. While our standard grade sits at ≥99%, we regularly refine and supply premium 99.5%, 99.9%, and ultra-high 99.999% optical-grade batches for sensitive electronic substrate and laser crystal growth applications.
No complex refrigeration is needed. Just keep the material tightly sealed in a dry, well-ventilated warehouse environment. The main priority is keeping it physically isolated from aggressive acids and strong oxidizers.
