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]
Refractory metals are a class of metals that are extraordinarily resistant to heat and wear. The expression is mostly used in the context of materials science , metallurgy and engineering . The definition of which elements belong to this group differs.
In planetary science, any material that has a relatively high equilibrium condensation temperature is called refractory. [1] The opposite of refractory is volatile.. The refractory group includes elements and compounds like metals and silicates (commonly termed rocks) which make up the bulk of the mass of the terrestrial planets and asteroids in the inner belt.
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.

The refractory period is the time when it’s difficult — if not impossible — to get aroused again after you climax during intercourse or solo pleasure. It is sometimes referred to as part of ...
The Harbison-Walker Refractories Company is a national historic district and historic refractory brick manufacturing complex which is located in Mount Union in Huntingdon County, Pennsylvania. It originated as the Star Firebrick Company on March 7, 1865, with Articles of Association by a group of Pittsburgh and Allegheny residents.
The refractory period is the period of time after discharge during which you won’t be able to get aroused. This period can last just a few minutes or several hours (typically, the older you get ...
