The Weibull modulus is a dimensionless parameter of the Weibull distribution. It represents the width of a probability density function (PDF) in which a higher modulus is a characteristic of a narrower distribution of values.
Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3 N 4 (Trisilicon tetranitride) is the most thermodynamically stable and commercially important of the silicon nitrides, [6] and the term ″Silicon nitride″ commonly refers to this specific composition.
Kenneth Price (February 16, 1935 – February 24, 2012) was an American artist who predominantly created ceramic sculpture. He studied at the Chouinard Art Institute and Otis Art Institute (now Otis College of Art and Design) in Los Angeles, before receiving his BFA degree from the University of Southern California in 1956.
Zerodur is a lithium-aluminosilicate glass-ceramic manufactured by Schott AG. Zerodur has a near zero coefficient of thermal expansion (CTE), and is used for high-precision applications in telescope optics , microlithography machines and inertial navigation systems .
PPG expanded quickly. By 1900, known as the "Glass Trust", it included 10 plants, had a 65 percent share of the U.S. plate glass market, and had become the nation's second largest producer of paint. [4] Today, known as PPG Industries, the company is a multibillion-dollar, Fortune 500 corporation with 150 manufacturing locations around the world.
Influences of selected glass component additions on the bulk modulus of a specific base glass. [6] A material with a bulk modulus of 35 GPa loses one percent of its volume when subjected to an external pressure of 0.35 GPa (~ 3500 bar) (assumed constant or weakly pressure dependent bulk modulus).
Glass-ceramic from the LAS system is a mechanically strong material and can sustain repeated and quick temperature changes up to 800–1000 °C. The dominant crystalline phase of the LAS glass-ceramics, HQ s.s., has a strong negative coefficient of thermal expansion (CTE), keatite-solid solution as still a negative CTE but much higher than HQ s ...
The company was established in 1984. Its A shares and B shares were listed on the Shenzhen Stock Exchange and this made it become one of the first listed companies in China. It is headquartered in Shenzhen and production bases are located in Shenzhen, Guangzhou , Dongguan , Tianjin , Chengdu , Yichang , Suzhou and Hainan Province .
