Particles of foreign material in a metallic matrix. The particles are usually compounds (such as oxides, sulfides, or silicates), but may be of any substance that is foreign to (and essentially insoluble in) the matrix.
Contamination particles in raw material caused by defects in the casting process
Any metallic particles, foil, bubbles, sections of millefiori cane, pieces of contrasting-coloured glass or any other bodies embedded in the main body of the glass
Particles which are usually compounds, such as oxides or sulphides, but that could also be of any substance that is essentially insoluble in the steel matrix, eg particles of lead. nclusions may occur from several sources. They may be the result deliberate additions, e.g. deoxidation (indigenous) or undesirable, e.g. entrapped slag of refractories (exogenous).
Naturally occurring particles in the clay, such as sand or mineral bits.
Particles of impurities (usually oxides, sulfides, silicates and such) that are held mechanically, or are formed during solidifi?cation or by subsequent reaction within the solid metal.
Non-metallic particles, such as oxides, sulphides or silicates that are held within solid metal.
Aggregations of insoluble pigments, nutrients, or other materials in cytoplasm.
particles of matter visible in a gemstones
Basic geologic principle used in determining relative ages of rocks; particles of a pre-existing rocks incorporated into a sediment must be older than the rock including them.
The internal imperfections of a gemstone, these are naturally-occurring features usually consisting of different materials which became trapped inside the gem during its growth. They may consist of small, solid mineral particles, bubbles of gas or liquid-filled cavities of varying shapes.
Coarse, non-plastic particles in a clay body.
Particles of slag, dirt or ohter non-metallic substances in molten metal that are retained during solidification.
Non-metallic materials (usually oxides, sulfides and silicates) found within a metal matrix.
non-metallic, often undesirable impurities retained in steel during solidfication
Undesired materials in a solid matrix.
Particles of matter visible in a gemstone.
Foreign material or particles in a metal matrix. These are usually compounds, such as oxides, sulfides, or silicates, but may be any substance that is foreign to the matrix whether it is soluble or insoluble.
Particles of foreign material (such as oxides, sulfides or silicates) in steel as cast.
Particles of foreign material (usually chips, dirt, carbon, oxides) that are held mechanically on or within the metal.
A collective term for bubbles, metal and glass particles, and other foreign materials that have been added to the glass for decorative effects.
Small pieces of refractory materials, sand, slag or deoxidation products that have been trapped within the casting while it was solidifying.
Particles of oxides, silicates, sulphides, refractory materials, slag, etc., embedded in the metal.
Usually non-metallic particles contained in metal. In steel they may consist of simple or complex oxides, sulphides, silicates and sometimes nitrides of iron, manganese, silicon, aluminum and other elements. In general they are detrimental to mechanical properties but much depends on the number, their size, shape and distribution.
Particles of slag, refractory materials, sand or deoxidation products trapped in the casting during pouring solidification.
