Low Cement Refractory Castable - Refractory Materials For

Because of super fine powder replaces some of the calcium aluminate cement, so compared with other refractory materials, high alumina low cement refractory castable has the following advantages: It has low calcium oxide content, which reduces eutectic phase, thus increase the refractoriness, high temperature strength and slag resistance.

Lithium - Wikipedia

Lithium (from Greek: λίθος, romanized: lithos, lit. ''stone'') is a chemical element with the syol Li and atomic nuer 3. It is a soft, silvery-white alkali metal.Under standard conditions, it is the lightest metal and the lightest solid element.Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere or inert liquid such as

Rock Thin Sections (Petrographic Thin Section - Kemet

Another oxide usually found in refractories is the oxide of calcium (lime). Fire clays are also widely used in the manufacture of refractories. Refractories must be chosen according to the conditions they will face. Some appliions require special refractory materials. Zirconia is used when the material must withstand extremely high temperatures.
