摘要:

ABSTRACTA general discussion of the gaps in our knowledge of the basic raw materials of the ceramic industries and the contradictory results reported in the literature. The paper is a plea for the more complete and accurate study of the principal materials.

摘要:

ABSTRACTThis paper is a progress report of an investigation dealing with refractory bodies made of cyanite, either raw or calcined, and which was taken from a recently discovered deposit in India. The bodies were subjected to standard and modified laboratory tests for high grade refractories. Petrographic analyses indicated complete conversion to mullite in the test specimens and the results of the laboratory test indicate the bodies to be equal in quality to many so‐called “super‐refractories” now on the

摘要:

ABSTRACTThe dissociation of cyanite into mullite was studied. Bricks were made of various mixes and their properties are given. Twenty per cent is about the minimum amount of clay which will give the proper bond. It was found desirable in some cases to add MgO in small amounts to promote a crystalline bond between the dissociated cyanite grains and the bonding material. In Pt. II the phase rule equilibrium relations are discussed.

摘要:

ABSTRACTThe literature relative to the investigation was reviewed and criticized. Iron pyrite was added to clays in amounts varying from 0 to 5%. Test pieces 2×2×41/2 inches were fabricated by the stiff‐mud, and dry‐press processes. After firing to cone 8 these were subjected to load tests at 1350°C under oxidizing, neutral, and reducing conditions. Expansion and contraction values were plotted against time and temperature. Results under reducing conditions. Expansion and contraction increased with increase of pyrite c
