castable refractory has higher content of binding agent and moisture. Refractory castable materials not only can directly used as the furnace lining, but also can be made to be precast block.

Refractory metals are a class of metallic materials that offer superior heat resistance and very high melting points. While the exact definition of which elements are included in this group varies, this article centers on the four most widely used refractory metallic elements: tantalum, niobium, ...
In many industrial processes, rapid temperature changes are common, posing a significant challenge for insulation materials.Insulation Ceramic Fiber Boards are designed to resist thermalshock, meaning they can endure sudden temperature fluctuations without cracking or deteriorating. This resistance not only ...
This helps us to understand the meaning of t = 0 in solar system chronology. Moreover, our model offers a possible explanation for the existence of isotopic variations observed among refractory materials—that the anomalous materials formed before the collapse of the parent molecular cloud was ...
2). This matches the information in the supplier datasheet on the raw materials used for making this type of refractory bricks. Chromite is present in the samples as grains (primary chromite; Chr-P in Fig. 2), meaning that the chromite has not been modified by the firing step of the ...
Baseline characteristics were comparable between treatment arms for patients who had HSCT directly after study treatment and who never had on-study HSCT (See Supplementary Materials and Table S1). Among patients who had subsequent salvage therapy, outcomes were poor. As of the last patient/last ...
very hightemperatures. Composed principally ofceramics, refractories are employed in great quantities in themetallurgical,glassmaking, and ceramics industries, where they are formed into a variety of shapes to line the interiors offurnaces,kilns, and other devices that process materials at high ...
When compared to composite materials and ceramics, refractory metal alloys have been found to offer an alternative approach. Not only are they somewhat easier to work with, they still provide the desired high temperature- and load-bearing characteristics. ...
said raw materials comprising at least alumina (Al2O3), zirconia (ZrO2), silica (SiO2), sodium oxide (Na2O) and yttrium oxide (Y2O3),wherein said raw materials optionally further comprise calcium oxide (CaO), the quantities of said raw materials being determined so that said refractory produc...
