Web30 apr. 2024 · Based on the property of refractoriness, the refractories are usually classified usually in four classes. These are namely (i) super-duty, (ii) high-duty, (iii) intermediate duty, and (v) low duty. Super duty refractories have PCE (pyrometric cone equivalent) value ranging from 33-38. Web18 jul. 2013 · Tape casting was chosen as a means of producing aligned alumina platelets in the alumina composites in the hope of achieving high sintered densities. Two platelet sizes were used (3–7 μm, 0·6 μm thickness and 10–15 μm, 1 μm thickness), and platelet contents up to 20 vol.-% were produced for each platelet size.
