kvartskomposit

Kvartskomposit is a term found in Swedish-language sources that can refer to more than one concept depending on the field. In materials science and engineering, kvartskomposit often denotes a composite material in which quartz or quartz-like filler particles are dispersed in a polymer or other matrix. The addition of quartz filler is intended to increase stiffness, hardness, wear resistance and dimensional stability, while the resin or matrix provides toughness and processability. Such composites are used in applications where mechanical durability and chemical stability are important, including dental restoratives that employ quartz-filled resin composites, as well as industrial components and coatings. Filler properties (particle size, surface treatment such as silanization), loading fraction, and curing method influence properties and performance. Because the term is not strictly standardized, specific formulations vary by manufacturer and application.

In music theory and composition, kvartskomposit can refer to works or techniques based on the interval of a fourth, or to quartal or fourth-based harmony in which chords are built on fourths rather than the traditional triads constructed from thirds. In this sense, it is related to, but distinct from, common quartal harmony and experimental approaches of 20th-century music. The term is more common in Scandinavian-language discussions of music theory.

The exact meaning should be inferred from context, as "kvartskomposit" is not a single universally recognized term in English-language sources. See also quartz-filled composite; quartal harmony; quartal chord.
