There are some metals on the Earth that are quite rare, and one of them is Cerium. This rare metal is found in minerals like bastnasite, synchysite, zircon, allanite, hydroxyl bastnasite, monazite, and rhabdophane. The oxide of this metal is quite useful and is known as cerium dioxide, cerium oxide, ceria, or simply as ceric oxide. It is basically a yellowish white powder. 

The powdered form of cerium oxide is produced through the processes called calcination. Cerium hydroxide or cerium oxalate is used for this process. Cerium Oxide powder is somewhat hygroscopic in nature, and it also imbibes a little amount of carbon dioxide present in the atmosphere. 

More About Cerium Oxide Powder 

The nano form of cerium oxide often exhibits yellow color, which may get darker sometimes. The synthesis of cerium oxide nano particles can be done through the process of precipitation. In this process, cerium nitrate is used as the raw material, whereas for precipitation agent, ammonium acid carbonate is used. 

The powdered form of cerium oxide has numerous applications. When it comes to choosing a coating material for infrared filters then cerium oxide is widely preferred. This powder is also used for coloring plastics. Since cerium oxide is quite resistant to heat, for this reason it is used as alloy coatings. Cerium oxide powder is also quite useful for superconductors; it can be used as buffer layer in this case. Apart from the above mentioned uses, there are many more reasons why cerium oxide and its powdered form is produced.

Silica Nano Particles Are Replacing Others Because Of Easy Availability!

Silica is an element which most of the easily available on the surface of earth. The sand and the soil we step on are made of nothing but silica. All that needs to be done is purify this sand and get the element. This is one of the main reasons nano particles of silica is replacing all other majorly used nano particles.  Silica is used in various electronic appliances due to its semi conductor properties. Silica Nano Particles are replacing other nano catalysts, metallic or otherwise. The catalytic properties of nano sized silica particles are higher over the others due to coverage or large surface area and inertness of participation in the chemical reactions. Silica Nano Particles Are Making A Name In The Bio Technical Felid! Silica particles are being continuously researched to check how they can be adapted in the field of cellular functions. The most recent discoveries made showed that they can be used to negate some of the cellular activities. They can also be used t

Why is it Beneficial to Use Ball Bearing Rollers in Industries?

Image
With the development in technology, new innovation emerged out to increase convenience of human kind. This paved its way to the development of many machineries and gadgets. A bearing is a part of any machinery or gadget that helps to reduce friction between the parts.   Ball Bearing Rollers | Image Resource : indiamart.com The relative motion of metals will lead to friction and will result in fast wear and tear of machines. Ball bearings are types of bearing that play a significant role in supporting the parts of machinery move or roll with minimal friction. This helps in the smooth functioning of the machine with high efficiency and speed. With the ability to reduce friction when in motion, the ball bearings are used widely in many applications in industries. A ball bearing a rolling part consists of an inner and outer ring that is separated by a series of rotating spherical balls. This helps to reduce friction loads are applied whether it is a radial load or
