The present invention relates to a method for manufacturing at least one monolithic inorganic porous support (1) having a porosity comprised between 10% and 60% and an average pore diameter ranging from 0.5 μm to 50 μm, using a 3D printer type machine (I) to build, in accordance with a 3D digital model, a manipulable three-dimensional raw structure (2) intended to form, after sintering, the monolithic inorganic porous support(s) (1).

A ceramic liner can include a monolithic body having a surface portion and a bulk portion. The surface portion can have a thickness less than the total thickness of the monolithic body. The monolithic body can include an amorphous phase. The amorphous phase can be discontinuous. At least one member of the discontinuous phase can be embedded in the surface portion. The bulk portion can be substantially free of the amorphous phase. A method of forming a ceramic liner can include providing a furnace with a coating and a bulk material of the ceramic liner and heating the bulk material and the coating. In an embodiment, a coated lining form can be used to provide the coating. In a particular embodiment, the coating can be transferred to the bulk material from the coated lining form.

A sputtering target configured from a magnesium oxide sintered body, wherein a ratio of crystal grains of the magnesium oxide sintered body in which a number of pinholes in a single crystal grain is 20 or more is 50% or less. The present invention is a sputtering target configured from a magnesium oxide sintered body in which the generation of particles during sputtering is less.

The present invention provides an annealing separator composition, a grain-oriented electrical steel sheet and a method for manufacturing a grain-oriented electrical steel sheet. An annealing separator composition for a grain-oriented electrical steel sheet according to an embodiment of present invention comprising: on the basis of total solid 100 wt %, 5 to 70 wt % of mullite; and the remainder being magnesium oxide or magnesium hydroxide.

The invention provides a process for manufacturing ceramics and refractories comprising the steps of producing a porous powder comprising nanograin sized particles wherein the particles have a Young’s modulus value that is smaller in value compared to the same crystalline material; compacting and processing the powder such that the powder forms a stable homogeneous composite; and sintering the composite for a time and temperature to lead to uniform shrinkage of the composite to make a dense homogenous material.

A metallurgical vessel structure and method is provided for producing low-impurity Magnesia-Carbon reclaimed aggregate suitable for reuse in the production of high purity Magnesia-Carbon refractory. A metallurgical vessel is assembled with a non-reactive or chemically similar backup lining. The entire height of the working lining wall is Magnesia-Carbon brick suitable for reuse. The working lining is exposed to a metal making high temperature process, and the working lining is sequentially demolished. Due to the assembly of vessel, metallurgical practice, and ease of demolishing the vessel, there is little to no need for sorting, such that the used Magnesia-Carbon brick are easily converted into low impurity Magnesia-Carbon reclaimed aggregate. A refractory composed of low-impurity Magnesia aggregate reclaimed from the method is also contemplated.
