• Melting Point: 450 °C.
• Boiling Point: 990 °C.
• Brittle: It is a brittle and easily pulverized metalloid.
• Chemical Properties: Tellurium is chemically related to selenium and sulfur, and exhibits oxidation states of -2, +2, +4, and +6, with +4 being the most common. 

• Cadmium Telluride (CdTe) Solar Panels: Tellurium is used in the production of CdTe solar panels. 
• Media Layer of Rewritable Optical Discs: It is also used in the media layer of rewritable optical discs. 
• Thermoelectric Applications: Tellurium-based thermoelectric materials are used in devices like thermocouples and thermoelectric generators for temperature measurement and waste heat conversion. 
• Semiconductor Applications: Tellurium can be used as a precursor to prepare tellurium-based nanomaterials for semiconductor applications. 
• Quantum Dot Solutions: Tellurium is used in quantum dot solutions for fluorometric determination of bioactive compounds. 

Dosage

Tellurium powder is a dark grey-to-brown, amorphous powder with metallic characteristics, a brittle, mildly toxic, and rare metalloid, used in metallurgy, electronics, and solar power applications. 

Remarks

Personal Protective Equipment (PPE):

• Wear protective gloves: Choose gloves that are impermeable to tellurium. 
• Wear protective clothing: Wear clothing that covers exposed skin. 
• Wear eye protection: Use goggles or a face shield to protect eyes from dust. 
• Wear a dust mask: Use a dust mask (like an N95) to prevent inhalation of dust.
