Overview of Silicon Nitride

Silicon Nitride (Si₃N₄) is a critical ceramic material renowned for its exceptional mechanical properties, high-temperature resistance, and chemical stability. It is widely used in the fabrication of high-temperature structural components, bearings, cutting tools, and electronic devices. Silicon Nitride can be prepared through methods such as reaction sintering or hot pressing, resulting in two crystalline forms: α-Si₃N₄ and β-Si₃N₄, depending on the production process.

Features of Silicon Nitride

High Hardness and Wear Resistance: Silicon Nitride boasts remarkable hardness and wear resistance, making it ideal for high-performance cutting tools.

Thermal Stability: It maintains excellent mechanical properties at extremely high temperatures, with a maximum usage temperature exceeding 1200°C.

Good Chemical Stability: It shows great resistance to corrosion by most molten metals and acid-base solutions.

Low Density: Compared to metal materials, Silicon Nitride has a lower density, beneficial for reducing the weight of structural components.

Excellent Electrical Insulation Properties: It is a preferred choice for electronic packaging materials.

Specification of Iridium Metal 99.95%,Pure 3n7 Iridium Powder

This iridium metal powder is 99.95% pure. We call this purity level 3N7. Iridium is a very rare precious metal. It belongs to the platinum group metals. This powder form makes it easy to handle and use in various processes.

The powder particles are very fine. You get high surface area. This is important for chemical reactions and catalysis. The purity is guaranteed at 99.95%. This means minimal impurities. Impurities can affect performance. We control quality carefully.

Iridium is incredibly dense. It is one of the densest elements. It also has an extremely high melting point. Iridium melts above 2400 degrees Celsius. This makes it suitable for extreme heat environments.

Corrosion resistance is outstanding. Iridium handles almost all acids. It resists attack by aqua regia. Aqua regia dissolves gold and platinum. Iridium stands strong. This property is vital for harsh chemical use.

Its hardness is significant. Iridium is quite hard for a metal. This hardness contributes to wear resistance. Parts made from iridium last a long time.

Electrical conductivity is good. Iridium conducts electricity reliably. Thermal conductivity is also respectable. These traits support its use in electronics.

Major applications exist. Iridium powder is used in spark plugs for aircraft engines. It provides longevity under high stress. The chemical industry uses it for crucibles. These hold molten reactive materials. Catalysts often contain iridium. It speeds up important chemical reactions. Electrodes in chlor-alkali processes use iridium coatings. This is for chlorine production. High-end scientific equipment needs iridium parts. It performs where other metals fail.

Applications of Iridium Metal 99.95%,Pure 3n7 Iridium Powder

This iridium metal is 99.95% pure. People call it 3N7 Iridium. It’s very rare and expensive. Iridium is one of the hardest metals. It resists corrosion extremely well. It handles very high temperatures. These properties make it valuable for tough jobs.

Solid iridium metal finds use in demanding situations. It works well for crucibles. These crucibles grow special crystals. The crystals are for lasers and electronics. Iridium makes parts for glass manufacturing. Equipment melts glass at high heat. Iridium lasts there. It serves in spark plugs for aircraft engines. These plugs fire reliably under stress. Iridium is used in deep-water electrical contacts. Salt water doesn’t damage it easily. It appears in some high-end pen tips. The tips resist wear for years.

Pure iridium powder (3N7) is very fine. This powder form is crucial for catalysts. Catalysts speed up chemical reactions. Iridium catalysts help make nitric acid. Nitric acid is vital for fertilizers. They are used in hydrogen fuel cells. Fuel cells need efficient catalysts. Iridium powder coats electrodes. Electrodes face harsh conditions. The coating protects them. It is applied in thin layers. This is called sputtering. Sputtering creates coatings for electronics. These coatings conduct electricity well. They resist corrosion strongly. Iridium powder is sintered. Sintering fuses powder into solid shapes. This makes components for specialized equipment. The equipment needs high heat tolerance. It needs chemical stability. Sintered iridium provides this.

Scientists use both forms of iridium. They need pure materials for experiments. Iridium helps in research labs. It aids in developing new technologies. Industries rely on its unique performance. It solves problems where other metals fail. Iridium handles extreme environments. It lasts a long time. This justifies its high cost.

5 FAQs of Iridium Metal 99.95%,Pure 3n7 Iridium Powder

What is Iridium Metal 99.95% Pure Powder?
It’s very fine iridium powder. The purity is 99.95%. This means almost no other elements are mixed in. We call this 3N7 grade. Iridium is a rare, hard metal. It belongs to the platinum group metals. This powder looks dark gray or black.

Why is Iridium Powder so Expensive?
Iridium is one of the rarest elements on Earth. It’s much harder to find than gold or platinum. Mining and refining it takes a lot of work. The process to make it 99.95% pure is complex. High demand and low supply keep the price high.

What are the Main Uses for this Powder?
It’s used where extreme durability matters. Spark plugs in high-end engines often use iridium tips. It goes into crucibles for growing crystals in labs. The chemical industry uses it as a catalyst. Electronics need it for some critical contacts. Medical devices might use it for parts too.

Is Iridium Powder Difficult to Handle?
Yes, handle it carefully. It’s a very dense powder. Don’t breathe it in. Always wear gloves and a mask in a ventilated area. Keep it away from strong acids or oxidizers unless you know it’s safe. Store it sealed tightly in a cool, dry spot.

What Makes Iridium Special Compared to Other Metals?
Iridium has incredible properties. It resists corrosion better than almost any metal. Almost nothing attacks it, even at high heat. It has a very high melting point. It’s also extremely hard and dense. A small piece of iridium feels very heavy for its size. Think of lead, but much heavier. These traits make it vital for tough jobs.
