Know the Uses of Reaction Bonded Silicon Carbide

Silicon carbide is popularly known as carborundum. The compound is made up of silicon and carbon elements and their chemical formula is SiC. The compound is naturally found as moissanite. This is used as an abrasive for which huge amounts of the compound is produced every year.

Do you know that this compound has varied uses? If not, continue reading this article to find out about the uses of the reaction bonded silicon carbide compound.

For Structural Materials

The compound is often used in bulletproof vests and composite armor. They also serve as shelving and support materials in high-temperature areas like kilns for glass fusing, firing ceramics, etc. The SiC kiln shelves are used because they are light in weight than the traditional alumina shelves.

As A Strong Catalyst Support

Reaction bonded silicon carbide exhibits a natural resistance property to oxidation. This, it is chosen as a heterogeneous catalyst to support oxidation reactions of hydrocarbons, like n-butane to maleic anhydride.

In Steel Production

When dissolved in basic oxygen furnace the compound can be used to make steel. The excess energy generated in the furnace allows processing of more scrap materials same as of hot metals.

As Abrasive Material and Cutting Tools

Silicon carbide is durable. Hence, they are used popularly as an abrasive in modern lapidary. The hardness of it makes it useful in the manufacturing industries for works like water-jet cutting, grinding, sandblasting and honing.

The finer particles of silicon carbide are fixed to paper to make sandpapers and grip tape for skateboards.

In Electric Systems

They are greatly used in the electric voltage purposes as silicon has a greater voltage acceptance. The earliest use of this compound was in the lightning arresters. Because of the voltage-dependent resistance, columns of carborundum pellets were used to connect the power lines with the earth. So, when lightning strikes the excess voltage will be passed to the earth harmlessly.

If switches are made out of them they can be placed in series. As they are good for high voltage requirements they can easily reduce the complexity of a system.

As Carborundum Printmaking

Another use of SiC compounds is collograph printmaking technique commonly known as Carborundum printmaking. On the surface of an aluminum plate, the Carborundum grit is applied to a paste. When the paste becomes dry the ink application is done. The ink gets trapped in the granular surface. When the ink is wiped off the bare areas the ink plate is printed onto paper. The painted marks embossed on the paper is the resultant print.

Computer Based Examination – All You Need To Know

With an abrupt rise in technology, we experienced the ultra modern tools to enhance our style of living. This has even parted the traditional examination system to active computer based exam. Earlier, it was registrations that will take near about 4-5 months to enroll the interested set of candidates by filling and submitting a long list of documents. Now, the entire selection ranging from the registration, admit card generation, distribution of admit cards, examination and result declaration, all gets winded up in the same time frame. This has reduced the unnecessary human effort that requires more time and concentration to present the final reports. Along with this, the overall expense to conduct an examination has also reduced a major extent via CBT (Computer based Test) examination system.

Listed below are a few of the important advantages of appearing in the computer based test;

- Time Management
The online examinations demand less of human interaction. Earlier, the students have to listen to the invigilator, require more time to highlight the correct response and make use of specific pen or pencil that will be acceptable to mark an answer.

- Seamless Internet Connection
The computer based exam is conducted using a Local Area Network (LAN). This offers a glitch-free exposure to the student for examination. In these exams, there are no worries of question paper leaking or cheating among the adjusting set of applicants.

- Basic Knowledge of a Computer
Candidates appearing in a system based examination just require basic knowledge of computer. This includes the familiarity to operate a keyboard and mouse. Meanwhile, an aspirant does get the option to go back and review the previous responses marked for the questions.

- Easy Amendment to Marked Responses
This is an add-on feature over the pen-pencil based examination. Using this, a student can easily review the responses marked and change the answer if required to do so in a computer based test. Where, as in a pen-pencil based paper the student cannot change the response if marked in an OMR sheet by pen. In order to mark correction if the candidate marks two responses for a question then would be considered as a negative answer for the OMR based question paper.

- Rough Sheets for Calculations
No worries to the rough work, each of the students will get adequate rough sheets to solve the numerical problems with ease. This helps them to easily conclude the answer for long and lengthy problem that requires more of calculations and analysis.

- No Partiality
While appearing in a computer based test the candidate will get exactly the same time to solve and submit the responses for the examination. Once a student, clicks on start button then only the timer gets started for the defined duration by the examination authorizes. With seamless internet connection the student has to mark the tentative set of responses. This provides fair allocation of time and resources to all the competing students assuring a transparent selection hierarchy.
