What does the packaging of rare earth metal products look like?

REE metal: Vacuum packaging, oil seal plus vacuum for rare earth metals that are easily oxidized (La, Ce, Eu, Sm, etc.).

 

What are the types of rare earth metals?

Reduced and distilled. Distilled has higher purity, mainly these elements: Y、Yb、Sc、Tm、Lu

 

Price Calculation of Rare Earth Compounds.

In rare earth industry, a formula is used to calculate the actual prices of rare earth compounds, such as carbonate, hydroxide and chloride: Actual price of rare earth compound = Price of 100% of TREO (Total rare earth oxide) X Percentage of TREO in the compound. For instance, if price of a cerium carbonate [Ce(CO3)3·xH2O] is quoted as TREO: 45%, Price: $7.63/kg X TREO. Thus, the actual price of the Cerium carbonate is $7.60/kg x 45% = $3.42/kg.

 

What are REE?
REE or Rare Earth Elements are 17 chemical elements.
The group of the rare earth elements is sub-divided in the heavy rare earth elements (HREE) and the light rare earth elements (LREE):

LREE = light rare earth elements (Sc, La, Ce, Pr, Nd, Pm, Sm, Eu, and Gd; also known as the cerium group)
HREE = heavy rare earth elements (Y, Tb, Dy, Ho, Er, Tm, Yb, and Lu; also known as the yttrium group)

Are Rare Earth Elements actually ‘rare’?
They were thought to be when they were discovered in the late 18th century. However, it is hard to find them in concentrations that are economically viable to exploit and hence they are ‘rare’. The strict mining laws in European countries make these particularly valuable for Europe. Rare earth metals are particularly challenging to extract because they are often found together and it requires a lot of chemistry and metallurgy to separate them from each other and purify them. These mines also typically contain radioactive thorium, which has to be handled separately.

 

What are the most important properties of REEs?
Magnetism, luminescence, and strength.


Where are REE used?
Their properties, notably as light-weight magnets, make them key to the ongoing miniaturization of electronics and the growth of green technologies. They are used in a wide range of products we use every day, including hard drives, earbud speakers, microphones in small gadgets, smartphones, flat-screen TVs, automotive application, motors, generators, etc.

** Phosphor is the luminescent material critical to many lighting applications, especially LEDs. Most white LEDs are in fact blue LEDs with a phosphor coating. Phosphor absorbs the light at the blue wavelength and reemits the photons at longer wavelengths.

Which are top three nations with the most REE reserves in the world?
Approximately half (55 million MT) of the world’s total reserves (130 million MT) is in China. The next biggest reserve of about 22 million MT is in Brazil. Australia stands third with 3.2 million MT of REE reserves.

Which are the top three nations in production of rare earth elements?
1. China (Almost 92-95% of REEs production is in China). Mine Production: 105,000 tons
2. Australia. Mine Production: 10,000 tons
3. United States. Mine Production: 4,100 tons

Which are the most important ores of the REEs?
Rare earths are relatively abundant in the Earth’s crust, but discovered minable concentrations are less common than for most other ores. World resources are contained primarily in bastnäsite and monazite.
Bastnäsite deposits in China and the United States constitute the largest percentage of the world’s rare earth economic resources, while monazite deposits in Australia, Brazil, China, India, Malaysia, South Africa, Sri Lanka, Thailand, and the United States constitute the second largest segment.

What else is interesting about REE?
Scandium (Sc) is more abundant in the Moon than on Earth.
Samarium (Sm) chloride taken internally in the proper quantity will combine with alcohol and keep you from becoming drunk
Europium (Eu) is used in anti-counterfeiting fluorescent phosphors in Euro banknotes
Ytterbium (Yb) lasers are used to drill into diamonds to remove imperfections.
Lutetium (Atomic Number 71) is named after Lutetia where it was first found, the city that later became Paris.

 

Are the CERAMICS products environmentally friendly?

-Ceramics uses clay as a raw material, a natural element respectful of the environment. On top of that, all glazes and varnishes used in the production are lead and cadmium free. Altogether the final result is environmentally friendly.

 

What types of ceramic do you supply?

-We offer the full range of technical ceramics from machinable grades like Macor and Shapal to materials that require diamond grinding like alumina, zirconia, carbides, and nitrides. We can machine and supply virtually any ceramic material. This allows us to optimize the material selection and design what is right for you the customer, rather than what is right for our capability.

 

Can I machine the ceramics myself?

-The harder ceramics like alumina and zirconia will require diamond tooling but other materials can be machined. Getting the right result does take time, experience, and semi-specialized tooling, but it can be done and many of our customers take advantage of this when they need extremely fast solutions in-house.

 

Can I purchase finished components?

-We have a dedicated ceramics machining facility, including 4th and 5th axis machining. Because of this, our prices and response rates are very competitive. We will also certify and guarantee all the ceramics we supply. You can send us an inquiry for more information.

 

I hear a lot about ceramics but I never see them. Are companies still looking for ways to use them?

-Advanced ceramics are used in more everyday products than you can imagine. Alumina is used in house fuses, tap seals, and central heating water pumps. Zirconia can be found in hair straighteners and glass-ceramic cooker hobs. Silicon nitride bearings and turbochargers can be found in most cars as can silicon carbide pump parts. Boron nitride is used extensively in make-up products from face powders to lipsticks. Ceramics are all around us but seldom noticed.

 

What is the maximum size of the ceramic products that I can purchase?

-300mm x300mm x 55mm is the maximum size and we can supply any smaller size or shape on request. We also carry many standard sizes of ceramic bars, rods, and sheets in stock for quick delivery. We are happy to discuss supplying fully machined components produced in our in-house facility. A thickness of 60mm may be possible in some applications.

 

What is the maximum size of Shapal I can purchase?

-We have recently been able to increase the maximum size availability of Shapal to 300mm x 300mm x 64mm. We carry many standard sizes of Shapal in stock and can supply fully machined components or non-standard sizes on request.

 

Can I have a free sample of your magnets?

Our company’s policy does not allow us to send out free samples. We keep our operation overhead low so that we can offer our customers our quality magnets at very competitive prices.
