Typical and ongoing research includes Bi 2 Te 3, and La 3-x Te 4, etc. Bi 2 Te 3 is widely used from energy conversion to sensing to cooling due to its great TE properties. The BiTe-based TE material can achieve a conversion efficiency of 8%, an average zT value of 1.05 for p-type and 0.84 for n-type bismuth telluride alloys. [ 81 ]
Minerals containing the chemical element tellurium Note (New Dana Classification): Telluride minerals are in the category: Sulfides and Sulfosalts (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.) too
There are 39 known isotopes and 17 nuclear isomers of tellurium (52 Te), with atomic masses that range from 104 to 142. These are listed in the table below. Naturally-occurring tellurium on Earth consists of eight isotopes. Two of these have been found to be radioactive: 128 Te and 130 Te undergo double beta decay with half-lives of, respectively, 2.2×10 24 (2.2 septillion) years (the longest ...

Tam Cốc – Bích Động is a popular tourist destination in north Vietnam and part of the Tràng An Scenic Landscape Complex UNESCO World Heritage site. [1] It is located in Ninh Binh province, near the village of Tam Cốc. The closest city is Hoa Lư.
Tellurite is a rare oxide mineral composed of tellurium dioxide (Te O 2).. It occurs as prismatic to acicular transparent yellow to white orthorhombic crystals. It occurs in the oxidation zone of mineral deposits in association with native tellurium, emmonsite and other tellurium minerals.
The Ho Chi Minh City–Long Thanh–Dau Giay Expressway (Vietnamese: Đường cao tốc Thành phố Hồ Chí Minh-Long Thành-Dầu Giây) is an expressway section of the Expressways of Vietnam, 55.7 km long and has its starting point at Long Truong intersection in Thủ Đức and the end point at Dầu Giây Interchange, Thống Nhất district, Đồng Nai.
Tellurite is a oxyanion of tellurium with the formula TeO 2− 3. It is the ion of tellurous acid, and is chemically related to tellurium dioxide (TeO 2), whose mineral appearance also bears the name tellurite. Tellurites are typically colorless or white salts, which in some ways are comparable to sulfite. [3]
