molybdenum silicon compound

<p>Molybdenum disilicide is a molybdenum silicon compound, because the two atoms of the radius difference is not, electronegativity is relatively close, so it has a similar nature of the metal and ceramics. Melting point up to 2030 ℃, with conductivity, at high temperatures to form a silicon dioxide passivation layer to prevent further oxidation, the appearance of  [url=http://modernoutdoordecking.com/good/862.html]low cost beauty housing plans[/url] gray metal color, derived from its tetragonal α-type crystal structure, there are hexagonal but unstable Β-modified crystal structure .</p><p> Insoluble in most of the acid, but soluble in nitric acid and hydrofluoric acid. Although molybdenum disilicide [url=http://modernoutdoordecking.com/good/861.html]railroad ties landscaping[/url]  has a high oxidation resistance and a Young's modulus at temperatures above 1000 ° C, it is brittle at low temperatures and additionally has a creep capacity that exceeds 1200 ° C and limits its application as a structural material, But combined with other materials as a composite material to provide mobile effect.</p><p> Molybdenum disilicide and its based materials are usually made from sintered. By plasma spraying  [url=http://modernoutdoordecking.com/good/860.html]artificial insulated wall panels[/url] can be used to produce dense monolithic and composite forms of the material, for rapid cooling, usually also contains a small amount of β-modified molybdenum disilicide. Since the resulting heating element can operate at 1800 ° C, it can be used for electric furnaces used in laboratories and production environments, producing glass, steel, electronics, ceramics, and other heat-treated materials. Although it is brittle, it can not  [url=http://modernoutdoordecking.com/good/859.html]best wood plastic use terrace ireland[/url]   be aged under high power operation, and its resistivity does not change with time. In the low oxygen environment, because the passivation layer is not easy to form, so the maximum operating temperature should be reduced.</p>
