Key Traits

You can tell precious metals by their special features. These metals do not rust or break down, so they last a long time. They look shiny and are worth a lot in many places. Scientists use special tools to find out how much of each metal is there, even if it is a tiny amount. The table below shows how exact these tests can be:

These metals are often found in very small amounts. Scientists use careful methods to find them, which helps make sure the results are right.

Gold and Silver

Gold and silver are the most famous precious metals. You can find them in jewelry, Münzen, and electronics. Gold does not lose its shine or color over time. Silver lets electricity flow better than any other metal, so it is used in electronics and factories. Studies show gold nanoparticles are usually smaller than silver ones when made the same way. Gold particles can get bigger as time goes on, but silver particles usually stay the same size. This helps explain why gold and silver act differently in products.

A study that lasted 52 years showed gold and silver prices change with money values. When the dollar or euro changes, the prices of these metals also change. This is why many people watch the market closely.

Other Precious Metals

There are other precious metals besides gold and silver, like platinum, Palladium, rhodium, iridium, ruthenium, and osmium. Each one has its own special uses. Zum Beispiel, platinum does not get damaged by heat or acids, so it is used in jewelry and medical tools. Palladium can take in hydrogen, so it is good for dental work and storing hydrogen. The table below shows some of these metals and what makes them special:

These special features make precious metals important for many products and jobs.

Precious Metal Alloys

Alloy Basics

You often see precious metals mixed with other elements to create alloys. An alloy forms when you combine two or more metals in different amounts. This process changes how the metal acts. Zum Beispiel, you can mix gold with copper or silver to make it stronger. Scientists use special methods to control the mix. They look at how fast each metal joins in and how much of each is present. The final precious metal content depends on these steps. Even small changes in the mix can affect how the metal melts or how it handles heat. You can see these effects during casting, where the right mix helps prevent cracks.

Tip: The way you mix metals can change how they behave. Careful control during alloy creation leads to better results.

Why Alloys Matter

Alloys play a big role in making precious metals useful for more jobs. When you add other elements, you can make the metal harder, stronger, or more resistant to rust. Studies show that adding small amounts of elements like chromium or molybdenum can greatly improve corrosion resistance. Zum Beispiel, a high-entropy alloy made from gold, Kupfer, nickel, Palladium, and platinum reached a yield strength of 820 MPa, which increased to 1170 MPa after more work. This means the metal can handle more force without breaking. You also see that thousands of alloy types exist to meet different needs. These changes help with recycling and make sure the metal can be used again.

  • Chromium helps stop rust in stainless steel.

  • Manganese removes harmful sulfur.

  • Silicon helps clean the metal during making.

  • Gold alloys are used in electronics because they resist corrosion and conduct electricity well.

Common Compositions

You find many common mixes of precious metals in nature and industry. One example is electrum, a natural alloy of gold and silver. Electrum usually has between 50% Und 95% gold by weight, with most samples around 92% Gold concentration. This range shows how precious metal content can change based on where you find it or how you make it. In jewelry, you often see gold mixed with copper or silver to make it harder and more durable. Each mix gives the metal new properties, making it fit for different uses. When you do testing, you check the exact mix to know the value and use of the metal.

Precious Metal Analyzer Methods

RFA AnalysatorS

You can use xrf analyzers to quickly check precious metals. These analyzers use X-rays to see what elements are in your sample. You do not have to cut or damage the metal. This means the test does not hurt your jewelry or coins. Xrf analyzers are great for checking many types of metal. You just put the sample in, press a button, and get results fast. People like xrf analyzers because they are quick and accurate.

Xrf analyzers, like the VRAY XRF analyzer, are small and easy to carry. You can bring them to stores, mines, or recycling places. You do not need to send samples to a lab. The analyzer gives you answers right away. You can test for gold, Silber, Platin, and more at the same time. This makes testing simple and saves time.

Note: Xrf analyzers do not harm your items. You can test valuable things safely.

Xrf analyzers work well and do not cost too much. You do not need a lot of training to use them. The analyzer can check over 20 elements at once. You get results that are almost as good as lab tests. The XRF analyzer is popular because it is reliable and gives exact results.

Here is a table that shows why xrf analyzers are helpful:

You can use xrf analyzers for many kinds of precious metal tests. They help you find fake metals, check purity, and know the value. Das VRAY XRF analyzer and others make testing easy for everyone.

Other Methods

There are other ways to test precious metals besides xrf analyzers. Some analyzers use optical emission spectrometry, or OES. OES sends a spark through the metal and reads the light. This method gives you a lot of detail and works for many metals. The VRAY XRF analyzer is not the only good tool, but it is very easy to use.

Some analyzers use inductively coupled plasma, or ICP, for testing. This method can find very tiny amounts of precious metals. You can use ICP-AES or ICP-MS analyzers for very good results. These analyzers need more work to get the sample ready, but they are very accurate. You can trust the results for purity and precision.

You may also see gravimetric titration and other chemical tests. These methods work well for checking purity and what is in the metal. Studies show gravimetric titration can recover almost all the metal, with very little error. This means you get very good results. The VRAY XRF analyzer and other new analyzers make testing faster and easier, but old methods are still used in labs.

Here is a table comparing some common analyzer methods:
