A composite composed of one or a plurality of principal strengthening compounds and at least one principal cemented refractory metal that is prepared by combining a suitable binary to senary borides and/or carbides with a unitary to binary principal refractory metal is disclosed. As compared with the conventional sintered cemented carbides, the composite of the disclosure not only possess high hardness and high toughness but also has various ratios of principal components since it is not prepared with equal mole during the process.

“Green”, ceramic tapes intended as building blocks for making complex, fully ceramic components and devices for electronic-, lab-on-chip-, and sensing applications, the manufacture of which comprises in sequence: I. mixing of a ceramic “green” paste, II. homogenisation of a ceramic “green” paste, III. dimensioning and optionally structuring the ceramic “green” paste, IV. drying of the dimensioned and structured ceramic paste, in which: step iii) is performed in a combination of an extruder and a calender, the extruder being provided with a circular extrusion die, splitting and unfolding the extruded tube to a flat, continuous tape strip, using methylcellulose or derivatives thereof as binder, and, an additional step chosen among cutting and punching the thus dimensioned and optionally structured “green” paste, thereby making thick, “green” tapes. A method for its manufacture is also contemplated.

Disclosed is an MgO target for sputtering, which can accelerate a film formation rate even when MgO is used as a target for sputtering in the formation of an MgO film. The MgO target for sputtering, which includes MgO and an electroconductive material as main components, and in which the electroconductive material is capable of imparting orientation to a MgO film when the MgO film containing the electroconductive material is formed by a DC sputtering.

An armor component including a body having a first portion including calcium boride compounds include non-stoichiometric calcium boride (CaB.sub.x) and stoichiometric calcium boride (CaB.sub.6) and having a density of at least about 80% theoretical density. In one aspect, the first portion can include a first phase comprising silicon carbide (SiC) and a second phase comprising calcium boride (CaB.sub.6). In another aspect, the first portion can further include a third phase comprising boron carbide (B.sub.4C).

A method of forming a shaped abrasive particle including extruding a mixture into a form, applying a dopant material to an exterior surface of the form, and forming a precursor shaped abrasive particle from the form.

An ornamental component has an ornamental face, and includes a titanium nitride sintered body containing nickel and niobium, and the titanium nitride sintered body contains a compound including nickel, niobium and titanium.

A method for producing a cermet composition, including mixing a first predetermined amount of a yttria stabilized zirconia powder with between 2 and 8 weight percent mu-metal powder to define a homogeneous admixture, oxidizing the mu-metal in the admixture, forming the homogeneous admixture into a green body, calcining the green body in a first reducing atmosphere to remove oxygen from the oxidized mu-metal to yield a calcined body, and sintering the calcined body in a second reducing atmosphere to yield a densified body having no more than 0.8% porosity. The densified body has a plurality of mu-metal particles distributed therethrough, a hardness of at least 1450 HV, flexural strength of at least 200 kPSI, and a relative permeability μ/μ.sub.o of at least 850.
