Refractoiy brick

Ceramics differ from some other materials (viz. metals, plastics, wood products, textiles) in a number of individual properties, but perhaps the most distinctive difference to a designer or potential user of eeramic ware is the particularity of the individual ceramic piece. Actually ceramics are not readily shaped or worked after firing, except for some simple shapes of limited sizes. Many ceramies are manufactured as standard items refractoiy bricks and shapes, crucibles, furnace tubes, insulators, thermocouple protection tube, fibre tubes etc. 

Survey your operations for potential exposure to hexavalent chromium. Employers can consult their suppliers or examine material safety data sheets or safety data sheets (MSDSs/SDSs) to identify Cr(VI)-containing materials that are present in the workplace. Also, remember Cr(VI) can be formed when performing hot work such as welding on stainless steel, melting chromium metal, or heating refractoiy bricks in kilns.

Carbon cathode blocks with collector bars are installed on a refractoiy layer that is made from fireclay bricks or dry barrier mixtures (DBMs). In A1 reduction cells, this refractory layer is usually called a barrier refractory layer because the temperature under the cathode blocks is relatively small if we think in refractory terms. The main purpose of the refractory barrier layer is to stop infiltration of electrolyte—in other words, to be the barrier for the infiltration of electrolyte.
