tavný

Tavná is the feminine form of the Czech adjective tavný, which means related to melting or fusible. The term is used predominantly in technical and scientific contexts to describe substances, properties, or processes that involve melting.

In materials science and metallurgy, tavný term is applied to concepts such as tavný bod (melting point) or tavná teplota (melting temperature). These expressions denote the temperature at which a solid substance becomes liquid under a given pressure. For example, the tavný bod vody (ice-water system) is 0 °C under standard conditions.

Tavná slitina, or fusible alloy, refers to a family of metals or metal mixtures with low melting points. Such alloys are designed to melt at relatively modest temperatures and are used in applications like fuses, soldering, and temperature control devices. Common examples include Wood’s metal, Rose’s metal, and Field’s metal. These materials enable practical functions such as automatic circuit protection or easy soldering in electronics and plumbing.

Etymology and usage notes: Tavný derives from the verb tavit, meaning to melt. The form tavná is used with feminine nouns (for example, tavná teplota, tavná slitina) to describe the melting-related properties or materials.
