آی تی Fundamentals Explained
Specially developed aerospace grades of silicone are stable from −70 to 220 °C,[eleven] these grades can be employed in the development of gaskets for Home windows and cabin doorways. through operation, aircraft endure big temperature fluctuations in a comparatively quick time period; in the ambient temperatures when on the bottom in hot international locations to sub-zero temperatures when traveling at higher altitude.
ترکیبات و ویژگی‌های کرم ضد آفتاب رنگی
چسب‌های آکواریوم نوع اسیدی پس از خشک شدن روی سطح بوی سرکه مانندی دارند. چسب‌های سیلیکونی اسیدی عمدتاً در درزگیری و ترمیم سطوح خارجی کاربرد دارند.
Pure SiC is colorless. The brown to black shade of the commercial solution outcomes from iron impurities.[39] The rainbow-like luster in the crystals is mainly because of the skinny-film interference of the passivation layer of silicon dioxide that forms to the floor.
Silicon's Homes are neither fish nor fowl. darkish gray in colour and with a really glossy glass-like sheen, it seems like a metal but is in actual fact quite a very poor conductor of energy, and there in some ways, lies the secret of its best success. the situation is the fact electrons are trapped, a little bit like pieces on a draughts board where no Areas are totally free. What can make silicon, and various semiconductors, special is the fact that it is achievable to promote among the list of electrons to an empty board - the conduction band - wherever they're able to transfer freely.
این پلیمرها معمولاً مقاوم به گرما بوده و به صورت مایع یا لاستیکی مانند موجود می‌باشند که برای کاربردهایی از قبیل: درزگیر و آب‌بند، چسب، روانکار، لوازم پخت‌وپز و همچنین عایق حرارتی و الکتریکی استفاده می‌شوند.
ناخالصی های معدنی می توانند به رنگ بنفش ، صورتی روشن یا سایر رنگ ها درآیند و در نتیجه سنگ های قیمتی یا نیمه قیمتی زیر را تولید می کنند:
علاوه بر این ، تولید دی اکسید سیلیکون در حین ساخت مواد شیمیایی کشاورزی اتفاق می افتد. با ورود به صنایع داروسازی ، به عنوان افزودنی مواد غذایی و داروها به جذب آب کمک می کند.
Silicate rocks - Individuals where silicon is surrounded tetrahedrally by four oxygen atoms - exist within an astonishing assortment, the differences remaining determined by how the tetrahedra developing blocks backlink collectively, and what other components are existing to complete the picture.
سیلیکون نقش بسیار مهمی در حفاظت در برابر بیماری‌های مختلفی همچون سل و سایر بیماری‌های مرتبط با غشای مخاطی دارد.
Silicone grease is often utilized with laboratory glassware to stop seizing. Silicone greases are used for lots of uses, which include bicycle chains, airsoft gun pieces, and an array of other mechanisms.
Silicon carbide can host issue defects while in the crystal lattice, that happen to be called colour centers. These defects can make solitary photons on demand and so function a platform for single-photon resource.
the colour changes to blue and black at bigger length with the resistor, and these darker crystals are significantly less pure. Nitrogen and aluminium are popular impurities, plus they have an effect on the electrical conductivity of SiC.[19]
Silicon carbides are very important abrasives and بررسی can also be Employed in lasers. Biological part Silicon is crucial to plants but its use in animal cells is unsure.
