Next, in 1995, RHI AG acquired a majority stake in its previous competitor Didier-Werke AG (founded by Friedrich Ferdinand Didier in 1834 when he acquired a brick and lime firing plant near Szczecin in Poland, and established the factory "Chamottefabrik F. Didier" in Podjuchy, thus becoming one of the first manufacturers of refractory bricks in ...
These opposing effects result in groups 5 through 7 exhibiting the most refractory properties. [8] Creep resistance is a key property of the refractory metals. In metals, the starting of creep correlates with the melting point of the material; the creep in aluminium alloys starts at 200 °C, while for refractory metals temperatures above 1500 ...
Calderys, a subsidiary of Imerys, is a multinational company specialized in producing heat resistant monolithic refractory products. [1] Calderys is headquartered at Issy-Les-Moulineaux on the outskirts of Paris, with over 2,000 employees and 18 plants in more than 30 countries.
In 1963, a 7-Eleven store near an Austin, Texas, university began to stay open all night for student shoppers. It was such a success that other stores in the chain adopted the 24/7 hours, and ...
Refractory bricks in a torpedo car used for hauling molten iron. In materials science, a refractory (or refractory material) is a material that is resistant to decomposition by heat or chemical attack and that retains its strength and rigidity at high temperatures. [1]

Fire clay in a furnace. Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick.The United States Environmental Protection Agency defines fire clay very generally as a "mineral aggregate composed of hydrous silicates of aluminium (Al 2 O 3 ·2SiO 2 ·2H 2 O) with or without free silica."
Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking or breaking.
