    en.wikipedia.org/wiki/Blueprint

    A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets introduced by Sir John Herschel in 1842. [1] The process allowed rapid and accurate production of an unlimited number of copies.

  5. Roasting (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Roasting_(metallurgy)

    The first reaction represents the chlorination of a sulfide ore involving an exothermic reaction. The second reaction involving an oxide ore is facilitated by addition of elemental sulfur. Carbonate ores react in a similar manner as the oxide ore, after decomposing to their oxide form at high temperatures. [6]

  6. Octasulfur - Wikipedia

    en.wikipedia.org/wiki/Octasulfur

    Octasulfur forms several allotropes: α-sulfur, β-sulfur, γ-sulfur, and λ-sulfur. λ-Sulfur is the liquid form of octasulfur, from which γ-sulfur can be crystallised by quenching. If λ-sulfur is crystallised slowly, it will revert to β-sulfur. Since it must have been heated over 115 °C, neither crystallised β-sulfur or γ-sulfur will be ...

    en.wikipedia.org/wiki/Sulfur_oxide

    Sulfur oxide refers to many types of sulfur and oxygen containing compounds such as SO, SO 2, SO 3, S 7 O 2, S 6 O 2, S 2 O 2, etc. Sulfur oxide (SO x) refers to one or more of the following: Lower sulfur oxides (S n O, S 7 O 2 and S 6 O 2) Sulfur monoxide (SO) and its dimer, Disulfur dioxide (S 2 O 2) Sulfur dioxide (SO 2) Sulfur trioxide (SO 3)

  8. Sulfur dioxide - Wikipedia

    en.wikipedia.org/wiki/Sulfur_dioxide

    Sulfur dioxide is an intermediate in the production of sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur combines with oxygen. The method of converting sulfur dioxide to sulfuric acid is called the contact process. Several million tons are ...

    en.wikipedia.org/wiki/Disulfur_diiodide

    Sulfur diiodide (SI 2) has finally been reported in an argon matrix at 9 K by the reaction of sulfur dichloride and iodine; however, this has been disputed.[6]Sulfur and iodine react in antimony pentafluoride or arsenic pentafluoride to form the S 7 I + ion, which is stable at room temperature, unlike other sulfur-iodine compounds.
