  2. Hafnium carbonitride - Wikipedia

    en.wikipedia.org/wiki/Hafnium_carbonitride

    Hafnium carbonitride (HfCN) is an ultra-high temperature ceramic (UHTC) mixed anion compound composed of hafnium (Hf), carbon (C) and nitrogen (N).. Ab initio molecular dynamics calculations have predicted the HfCN (specifically the HfC 0.75 N 0.22 phase) to have a melting point of 4,110 ± 62 °C (4,048–4,172 °C, 7,318–7,542 °F, 4,321–4,445 K), [3] highest known for any material.

  3. Paraffin wax - Wikipedia

    en.wikipedia.org/wiki/Paraffin_wax

    Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), [ 2 ] and its boiling point is above 370 °C (698 °F). [ 2 ]

  4. Closet flange - Wikipedia

    en.wikipedia.org/wiki/Closet_flange

    PVC closet flange with steel flange, before installation. In plumbing, a closet flange (also known as a toilet flange) is a pipe fitting (specifically, a type of flange) that both mounts a toilet to the floor and connects the closet bend to a drain pipe. The name comes from the term "water closet", the traditional name for a toilet.

  5. Glass-to-metal seal - Wikipedia

    en.wikipedia.org/wiki/Glass-to-metal_seal

    Gallium is a soft metal with melting point at 30 °C. It readily wets glasses and most metals and can be used for seals that can be assembled/disassembled by just slight heating. It can be used as a liquid seal up to high temperatures or even at lower temperatures when alloyed with other metals (e.g. as galinstan). [8]

  6. Microcrystalline wax - Wikipedia

    en.wikipedia.org/wiki/Microcrystalline_wax

    The melted wax can be cast to make multiple copies that are further carved with details. Jewelry suppliers sell wax molded into the basic forms of rings as well as details that can be heat welded together and tubes and sheets for cutting and building the wax models. Rings may be attached to a wax "tree" so that many can be cast in one pouring.

  7. Melting point - Wikipedia

    en.wikipedia.org/wiki/Melting_point

    The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.

  8. Wax - Wikipedia

    en.wikipedia.org/wiki/Wax

    The best-known animal wax is beeswax, used in constructing the honeycombs of beehives, but other insects also secrete waxes. A major component of beeswax is myricyl palmitate which is an ester of triacontanol and palmitic acid. Its melting point is 62–65 °C (144–149 °F). Spermaceti occurs in large amounts in the head oil of the sperm whale.

  9. Wax ester - Wikipedia

    en.wikipedia.org/wiki/Wax_ester

    The fatty acids of wax esters of certain zooplankton largely reflects the fatty acids of phytoplankton, and contain high amounts of C14 and C16, as well as 20:5n-3, 22:5n-3 and 22:6n-3 and monounsaturated C20 and C22 are the principal fatty alcohols.
