Silicon tetrachloride | SiCl4 - PubChem
Silicon tetrachloride is a colorless, fuming liquid with a pungent odor. It is decomposed by water to hydrochloric acid with evolution of heat. It is corrosive to metals and tissue in the presence of moisture. It is used in smoke screens, to make various silicon containing chemicals, and in chemical analysis.
Are there any non-metals other than graphite that …
2010/12/31· Conducting polymers are non-metals that conduct electricity through electron "hopping". Take for example, Polyaniline doped with HCl. I have to agree that pure water does not conduct electricity. Strictly sing, pure water does not contain any salt. Salts are
About | silicon carbide ceramic solutions
Silicon carbide is a man-made material manufactured through heating silica sand and carbon to high temperatures in the furnace technique. Silicon carbide is an extremely hard material (Mohs hardness 9), is chemically inert and does not melt.Silicon Carbide has a high thermal conductivity, a low coefficient of thermal expansion, is thermal shock and abrasion resistant and has strength at high
Piezoelectricity - How does it work? | What is it used for?
2019/11/9· Y ou''ve probably used piezoelectricity (pronounced "pee-ay-zo-electricity") quite a few times today. If you''ve got a quartz watch, piezoelectricity is what helps it keep regular time.If you''ve been writing a letter or an essay on your computer with the help of voice recognition software, the microphone you spoke into probably used piezoelectricity to turn the sound energy in your voice into
Lattice Type? | Yahoo Answers
2008/5/11· Compounds which are described as COVALENT NETWORK, silicon dioxide and silicon carbide, generally have very high melting points and very low vapor pressures; they do not conduct electricity. In a covalent network solid, all of the individual atoms making up the solid are held together in a giant lattice by covalent bonds.
Silicone grease - Wikipedia
Silicone grease is commonly used for lubriing and preserving rubber parts, such as O-rings.Additionally, silicone grease does not swell or soften the rubber, which can be a problem with hydrocarbon-based greases.It functions well as a corrosion inhibitor and lubricant for purposes that require a thicker lubricant.

Why do silicon wafers break easily? — Sewell Direct
Why do silicon wafers break easily? The fact that silicon wafers are easy to break is a material property: the type of silicon used in semiconductor wafers is single-crystal silicon. That means all the atoms are carefully aligned into a single crystal form. The wafers are sliced off of a single crystal of silicon pulled very slowly from a molten pool of ultra-pure silicon. One atom-sized
EPC - What is GaN?
Rise of Gallium Nitride Semiconductors The leading candidate for taking electronic performance to the next level and a reactivation of positive momentum of Moore’s Law is gallium nitride. GaN’s ability to conduct electrons more than 1000 times more efficiently than silicon, while being able to be manufactured at a lower cost than silicon has now been well established.
