Refractories and Classification of Refractories. Refractories are inorganic nonmetallic porous and heterogeneous materials composed of thermally stable mineral aggregates a binder phase and additives. The principal raw materials used in the production of refractories are normally the oxides of silicon aluminum magnesium calcium and irconium.
To provide a production process for silicon carbide ceramics by which a silicon carbide ceramic dewaxed body or sintered body each having strength capable of withstanding its handling and working can be produced and the sintered body when impregnated
The silicon carbide manufacturing process can be divided into two general steps the production of SiC crude generally SiC lumps having a diameter of 38 inch or more and the crushing and grading of the silicon carbide crude into finished sies of grains and powders for sale to customers.
To provide a readily sinterable silicon carbide powder which has a substantially stoichiometric composition and which provides a fine sintered body a silicon carbide ceramic sintered body having low resistivity and a method for producing the same.
201888difcult to manufacture owing to their wear and heat resistance capabilities. In this study for different process parameters and presents optimum laser process parameters for the fabrication of down to the micrometer details and must be sinterable to the desired density without cracking and fragmentation. These constraints require

2020324Silicon Carbide Grinding. The ceramic research group also investigated the comminution of silicon carbide using the attrition grinding process. In these studies a rounded silicon carbide grinding medium was produced by the prolonged autogenous milling of an angular silicon carbide material.
Silicon carbide is a poorly sinterable ceramic similar to silicon nitride. Sintering methods are divided into reaction sintering pressureless sintering hotpressing and hipping with additives. Reaction sintering consists of reaction bonding using SiCCSi mixtures and subsequently recrystalliing the silicon carbide compact. Read more

201117conditions were optimied for both materials silicon carbide and sinterable carbon or PAM meso cokes which are used in specific applications. The nearnet shaping of components made of liquid phase sintered silicon carbide LPSSiC was applied to the manufacture of mirror blanks for astronomical telescopes. As part of this work a
2020316Dense silicon bodies are obtained by a process in which granular silicon carbide a carboniable material and a carbonaceous material are mixed together the mixture is shaped as desired and then the shape is fired in the presence of more than the stoichiometric amount of silicon.
Fine grain graphite has been an important material for tribologically loaded components such as seals and bearings for almost a century. Requirements are becoming more severe and complex concerning miniaturiation higher normal loads and toxicological restrictions. Today stateoftheart production of high quality fine grain graphite from binder and filler begins to reach its technical and

2015122The U3Si2 formulation process used in this work is described in detail in Reference 3 and summaried here. Uranium silicide is formed from mixing powders of elemental uranium and silicon in near stoichiometric quantities. Uranium powder is created by a hydride dehydride process and silicon powder is created by mechanical crushing.
