Tungsten wire, due to its high melting point, low vapor pressure, high thermal stability, and controllable electron emission properties, is an ideal material for electron tube hot cathodes.

Although modern stage lighting is gradually incorporating new technologies such as LEDs and lasers, tungsten wire lamps (such as tungsten-halogen lamps) still hold a vital position in specific applications due to their high color rendering, continuous spectrum, and controllability.

Tungsten wire still holds a niche in decorative lighting due to its unique aesthetic and warm glow, particularly in retro and artistic settings. The following is an analysis of the specific uses and characteristics of tungsten wire in decorative lighting:

Tungsten wire, as a light source for retro lamps, is widely popular due to its unique optical characteristics and nostalgic aesthetics, especially in decorative lighting.

The application of tungsten wire light-emitting in incandescent light bulbs is primarily based on its high melting point and excellent thermal radiation properties. The following is a brief description of its specific applications and principles:

Tungsten wire has a wide range of uses. Its exceptional physical properties, such as its extremely high melting point (approximately 3422°C), excellent corrosion resistance, and good electrical conductivity, have led to its widespread application in industry, technology, and everyday life.

In a hospital imaging department, a patient lies on an examination table, about to undergo a CT scan. As the equipment activates, an invisible ray begins rotating around the patient’s body—this is the X-ray, capable of penetrating the body to clearly reveal internal structures, providing critical evidence for disease diagnosis. Behind these radiation applications, a key player operates quietly in the background: the tungsten alloy collimator. Though you may never have heard of it, it functions like a behind-the-scenes hero, influencing the effectiveness of radiation detection and treatment. Why is it entrusted with this responsibility, and what unique properties does it possess?

Radiotherapy equipment is a specialized medical device used for tumor radiation therapy, with its core function being the generation and delivery of high-energy rays (such as X-rays, gamma rays, electron beams, and proton beams) to damage the DNA structure of cancer cells, inhibiting their proliferation and thereby treating tumors. However, radiation is a double-edged sword—it can harm surrounding healthy tissues while targeting cancer cells. At this juncture, a seemingly inconspicuous yet highly critical component—the tungsten alloy collimator—plays a vital role. Acting like a "gatekeeper," it controls the direction and range of radiation, ensuring that rays target cancer cells as precisely as possible. So, what exactly is this tungsten alloy collimator, which plays a key role in radiotherapy, and how does it control radiation?

As a representative material among low-dimensional transition metal dichalcogenides, molybdenum diselenide (MoSe₂) is widely used in various fields such as photocatalysis, energy storage, solid lubrication, microelectronics, and optoelectronics due to its unique crystal structure and excellent thermodynamic properties. Below is an introduction to the basic information of this material.

As one of the most important raw materials for producing hard alloys, the particle morphology, size, particle size distribution range, and impurity content of tungsten carbide (WC) powder directly impact the quality and application of hard alloys. Based on particle size differences, WC powder is categorized into ultra-coarse tungsten carbide, micron tungsten carbide, submicron tungsten carbide, sub-nanometer tungsten carbide, and nano tungsten carbide. So, what are the advantages and disadvantages of submicron WC particles compared to other sizes?
