Polymeric precursors to a variety of non-oxide ceramics happen to be synthesized by reacting metal alkoxides with An array of polyhydric and monohydric alcohols (transesterification). The selection of alcohols controls the shape on the polymer and the stoichiometry in the coke made by charring the polymer in an inert environment.Purification and Si

The "authentic" modern day pipe joint, circa 1925; the Mechanical Joint remains in use primarily as a means for connecting fittings, valves, and similar appurtenances to a pipeline.Form – Both equally pipes and tubes is usually spherical. Nevertheless, tubes could be rectangular and square shaped too, whereas pipes are only at any time spherical
