Boron''s Chemical and Physical Properties - ThoughtCo

Boron filaments have high strength, yet are lightweight. The energy band gap of elemental boron is 1.50 to 1.56 eV, which is higher than that of silicon or germanium. Although elemental boron is not considered to be a poison, assimilation of boron compounds has a cumulative toxic effect.

Calcium sulfate | CaSO4 - PubChem

CALCIUM SULFATE is non-coustible. Decomposes to give toxic oxides of sulfur, but only at very high temperature (>1500°C). Generally of low reactivity but may act as an oxidizing agent: incompatible with diazomethane, aluminum, and phosphorus. Certain forms of …

Ytterbium - Element information, properties and uses

Ytterbium is named after the town of Ytterby near Stockholm in Sweden, and makes up the fourth element to be named after this town, the others being of course yttrium, terbium and erbium. Ytterbium was isolated in 1878 by Jean Charles Galissard de Marignac who was a Swiss chemist working at the University of Geneva at the time.

Carbide - Wikipedia

2019-4-13 · In chemistry, a carbide is a compound composed of carbon and a less electronegative element. Carbides can be generally classified by the chemical bonds type as follows: (i) salt-like, (ii) covalent compounds, (iii) interstitial compounds, and (iv) "intermediate" transition metal carbides. Examples include calcium carbide (CaC2), silicon

polypropylene | Properties, Definition, & Uses

Polypropylene, a synthetic resin built up by the polymerization of propylene.One of the important family of polyolefin resins, polypropylene is molded or extruded into many plastic products in which toughness, flexibility, light weight, and heat resistance are required. It is also spun into fibres for employment in industrial and textiles.

Rhodium - Element information, properties and uses

Rhodium chloride, that sounds much like sodium chloride, but the reselance is only superficial. First of all, my rhodium atoms were in oxidation state three, thus requiring three chloride ions for every metal ion, and then, of course, there is the royal colour.

Carbide-derived carbon - WikiVisually

History []. The production of SiCl 4 by high temperature reaction of Chlorine gas with Silicon Carbide was first patented in 1918 by Otis Hutchins, with the process further optimized for higher yields in 1956. The solid porous carbon product was initially regarded as a waste byproduct until its properties and potential appliions were investigated in more detail in 1959 by Walter Mohun.
