Why is Silicon a poor electrical conductor
Answered By: Alan Lewis Date: created: Oct 21 2020
silicon is a poor conductor of electricity due to the free electrons being locked in giant lattice structures, and being unable to move around and carry the charge that makes up electricity. Why is a diamond a poor conductor of electricity and a good conductor of heat?

Is silicon carbide harder than diamond
Answered By: Lucas Mitchell Date: created: May 22 2021
Moissanite is similar to diamond in several important respects: it is transparent and hard (9–9.5 on the Mohs scale, compared to 10 for diamond), with a refractive index between 2.65 and 2.69 (compared to 2.42 for diamond). Moissanite is somewhat harder than common cubic zirconia.

Is Phosphorus a good conductor of electricity
Answered By: Hayden Morgan Date: created: Sep 27 2021
It is a good conductor of electricity and is black in color. Red phosphorus is formed when white phosphorus is exposed to light or when heated, making it amorphous. The allotrope has polymeric structure and is used in the production of safety matches.

Is Diamond a good conductor of electricity
Answered By: Gregory Wood Date: created: Dec 02 2020
Diamond is a good conductor of heat but bad conductor of electricity. Electric current is caused due to availablity of free electrons in a crystal . In case of diamond, each carbon atom is covalently bonded with four other carbon atoms and hence no free electrons are available to conduct electric current.

Is pure silicon a conductor
Answered By: Oliver Hernandez Date: created: Jun 13 2021
Pure silicon is an intrinsic semiconductor and conducts electrons and electron holes released by atoms in the crystal on heating. The conductivity of pure silicon is quite low, hence it is not suitable as a circuit element for electrons and is doped with small amounts of other elements.

Is Silicon a good or poor conductor of heat
Answered By: Anthony Stewart Date: created: Mar 30 2021
Silicon emulates diamond’s properties somewhat (its crystalline and atomic bonding structure is analogous to diamond) by being quite a good heat conductor while being a semi-conductor. Highly poor silicon (‘chip’ or ‘solar’ grades) is a very poor conductor of electricity and cheaply available.

Why Graphite is a good conductor of electricity but Diamond is a non conductor of electricity
Answered By: Oswald Martinez Date: created: Sep 04 2021
12. Graphite can conduct electricity because of the delocalised (free) electrons in its structure. These arise because each carbon atom is only bonded to 3 other carbon atoms. However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons.

ProfessionalQuick Answer: Does Gold Scratch Easily?
Despite being stronger and more durable, platinum is a softer metal than 14k gold.This means it will get scratched a little easier than 14k gold would.However, an important thing to note is when gold is scratched, the gold is lost and it looks like a scratch. Does 10k gold scratch easily? As a result of its hardness, 10K gold jewelry is very durable, relatively speaking. In comparison, alloys such as 18K or 20K gold scratch much more easily, and jewelry made with them is easier to bend. Click here to see an extensive selection of 10K gold jewelry. Does 18k gold scratch easily? You won't usually find gold rings beyond 18K because they tend to get scratches and deformations way too easily.

ProfessionalWhy Does Ceramic Break So Easily?
“The hard ceramic fragments of broken spark plugs are great at breaking tempered glass.The reason is that the small, sharp, and hard ceramic fragments induce scratches that pierce through the residual stresses of the glass.Once the crack gets started, it quickly spreads.” Why does ceramic break glass so easily? When thrown with moderate speed at a side-window, a sharp shard of the exceptionally hard aluminium oxide ceramic used in spark plugs focuses the impact energy into a small enough area without blunting to initiate cracking, releasing the internal energy and shattering the glass. Can ceramic break easily? The rub with ceramics is that, while they're tough to scratch, they're* *more prone to cracking compared to metal.

ProfessionalQuestion: Why Are Ceramic Knives So Sharp?
Ceramic blades require substantially less work than metal knives.Traditional steel blades need to be honed and re-sharpened regularly in order to keep their sharp blades, but a ceramic knife has actually been proven to stay sharp for up to 10 times longer. Do ceramic knives stay sharp? When made by a good manufacturer they are delivered sharply. They stay sharp longer than the steel knives and, of course, do not rust. Also, many people experience the low weight of the knives to be comfortable. Ceramic knives have the disadvantage that they are difficult, if not impossible, to sharpen them yourself. Do ceramic knives ever need sharpening? Unless you are cutting other ceramics or diamonds, these knives should almost never get dull. Bone has a hardness of about 3.5, steel knives about 6.5 and ceramic knives about 9.5. Diamonds are 10. If you really want to sharpen them you will need…
