When it comes to biomedical applications, Ring Electrodes play a pivotal role in ensuring the accuracy and efficiency of various medical devices. These electrodes are often integrated with Radiopaque Marker Bands to enhance their visibility during imaging procedures. Ring electrodes are typically made from conductive materials such as Platinum-iridium alloy, which offers excellent electrical conductivity and biocompatibility. This makes them ideal for use in devices like pacemakers and neurostimulators, where reliable electrical contact is essential. One of the key advantages of using Platinum-iridium alloy in ring electrodes is its resistance to corrosion. This ensures that the electrodes maintain their performance over time, even when exposed to bodily fluids. Additionally, the alloy's radiopacity allows for easy tracking of the device during implantation and follow-up procedures. In some cases, ring electrodes are combined with Capillary tubes to facilitate the delivery of medic...

Marker bands are essential components in the medical device industry, particularly in the design of catheters and guidewires. Among the various types of marker bands, Radiopaque Marker Bands stand out due to their ability to enhance visibility under X-ray imaging. These bands are typically made from materials like Tantalum or Platinum-iridium alloy, which are known for their high density and radiopacity. Radiopaque marker bands are strategically placed on medical devices to help healthcare professionals accurately locate and position the device within the body. This is especially crucial during minimally invasive procedures, where precision is key. The use of Tantalum in these bands ensures that they are not only visible but also biocompatible, reducing the risk of adverse reactions. In addition to their radiopacity, marker bands must be durable and resistant to corrosion. This is where materials like Platinum-iridium alloy come into play. These alloys offer excellent mechanical prop...

Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. The most important properties of tungsten are high melting point and high density. Meanwhile, the hardness is high and its ductility is poor to other refractory metals. All the properties make tungsten metal hard to be machined, here we will introduce the machining process for tungsten tube & crucible, Plate, Sheet & Foil. As tungsten’s relatively poor machability, the process & machine selection is very important. It might be crack in the process seriously, or not able to reach the tolerance. The raw material and annealing process counts a lot too. After sintering, the tungsten blank will be forged, to make a higher density and better mechanical properties. Process of tungsten plate: Thicker plate or block is forged from ingot, and ground to tight tolerance. Thinner plate or sheet are made by hot rolling process, annealing if carried between each rolling. Annealing is to make the mater...

Magnetism is the basic property of matter as well as force, heat, electricity and light. Materials with ferromagnetism are usually called magnetic materials. The biggest characteristic of magnetic materials is the hysteresis behavior, that is, the magnetization M changes with the external magnetic field. When H returns from a certain state to zero, M still maintains a certain size. Only when the magnetic field is applied in the opposite direction M drops to zero, so that the reciprocal change of M with H is a loop instead of a single curve. Figure 1-1 shows a schematic diagram of a typical hysteresis loop. The main parameters describing the characteristics of the hysteresis loop are: (1) Residual magnetic induction Br, (or residual magnetic polarization Jr=AMr) (remanent magnetism for short) is the magnetic flux density when the magnetic field H=0 in the magnet; (2) The coercive force HcB (or intrinsic coercive force HcJ) is the reverse magnetic field H necessary for the magnetic...

The production efficiency of boron nitride produced by chemical vapor deposition is high, but this method is easy to introduce pores and impurities into the sintered body and anisotropy caused by hot pressing. This makes its application very limited, especially in high temperature and oxidizing environments. Pyrolytic boron nitride materials have excellent physical and chemical properties. Chemical vapor deposition (CVD) is an ideal choice for the preparation of high-purity and dense boron oxide materials. The structure, morphology and properties of the prepared pyrolytic boron nitride (PBN) may depend to a large extent on the process conditions. Most boron nitride prepared by chemical vapor deposition (CVD) is thin film, powder, etc., while bulk boron nitride is limited to highly anisotropic pyrolytic boron nitride, which cannot fully utilize the characteristics of structural diversity. The synthesis of boron nitride limits its application in a wider field. Therefore, there are relat...

Pyrolytic boron nitride is an anisotropic high-temperature ceramic with high electrical resistance and good thermal conductivity. It is suitable for applications requiring high strength, low thermal expansion coefficient and good thermal shock resistance. Pyrolytic boron nitride also has thermal shock resistance and is a superior sealant that protects graphite from corrosive environments, such as most molten metals, acids, and hot ammonia environments. It has been verified that pyrolytic boron nitride is also a very effective insulating material. Pyrolytic boron nitride is non-toxic and harmless under normal conditions, has no porosity, and has high purity, so it is easy to store and easy to process into crucibles, evaporation boats, plates, pipes, bottles and other utensils. Pyrolytic Boron Nitride (PBN) belongs to the hexagonal crystal system. It is an advanced ceramic material with a purity of 99.999%, acid and alkali resistance, oxidation resistance, good thermal conductivity, co...
