  2. Pyrotechnic composition - Wikipedia

    en.wikipedia.org/wiki/Pyrotechnic_composition

    Pyrotechnic compositions are usually homogenized mixtures of small particles of fuels and oxidizers. The particles can be grains or flakes. Generally, the higher the surface area of the particles, the higher the reaction rate and burning speed. For some purposes, binders are used to turn the powder into a solid material.

  3. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter.

  4. Pyrophosphate - Wikipedia

    en.wikipedia.org/wiki/Pyrophosphate

    Infobox references. In chemistry, pyrophosphates are phosphorus oxyanions that contain two phosphorus atoms in a P−O−P linkage. A number of pyrophosphate salts exist, such as disodium pyrophosphate (Na2H2P2O7) and tetrasodium pyrophosphate (Na4P2O7), among others. Often pyrophosphates are called diphosphates.

  5. Disodium pyrophosphate - Wikipedia

    en.wikipedia.org/wiki/Disodium_pyrophosphate

    Disodium pyrophosphate or sodium acid pyrophosphate (SAPP) [1] is an inorganic compound with the chemical formula Na 2 H 2 P 2 O 7. It consists of sodium cations (Na+) and dihydrogen pyrophosphate anions (H2P2O2− 7). It is a white, water-soluble solid that serves as a buffering and chelating agent, with many applications in the food industry.

  6. Dimethyl methylphosphonate - Wikipedia

    en.wikipedia.org/wiki/Dimethyl_methylphosphonate

    Dimethyl methylphosphonate is a schedule 2 chemical as it may be used in the production of chemical weapons. It will react with thionyl chloride to produce methylphosphonic acid dichloride, which is used in the production of sarin and soman nerve agents. Various amines can be used to catalyse this process.

    Pyroceram. Pyroceram is the original glass-ceramic material developed and trademarked by Corning Glass in the 1950s. [1] Pyroceram is an opaque, white, glass material, commonly used in kitchenware, glass stove tops, wood stove doors, etc.. It has high heat tolerance and low thermal expansion.

  8. Potassium persulfate - Wikipedia

    en.wikipedia.org/wiki/Potassium_persulfate

    Potassium persulfate is the inorganic compound with the formula K 2 S 2 O 8. Also known as potassium peroxydisulfate, it is a white solid that is sparingly soluble in cold water, but dissolves better in warm water. This salt is a powerful oxidant, commonly used to initiate polymerizations.

  9. Pyroprocessing - Wikipedia

    en.wikipedia.org/wiki/Pyroprocessing

    Pyroprocessing (from Greek Πυρος = fire) is a process in which materials are subjected to high temperatures (typically over 800 °C) in order to bring about a chemical or physical change. Pyroprocessing includes such terms as ore-roasting, calcination and sintering. Equipment for pyroprocessing includes kilns, electric arc furnaces and ...
