Pressureless sintering SiC, also known as sintered SC (SSiC). It was previously believed that SiC was impossible to sinter without pressure. However, in 1973, Prochazka, a ceramic scientist at GE in the China, first discovered that the submicron β-SiC powder prepared by the gas phase method, with the introduction of a small amount of […]
Customized rods made of alumina (Al2O3) ceramics, also known as resistance electric heating ceramic rods. Alumina ceramic rods are commonly used in electric heating elements, such as heating rods, where ceramic materials are widely used because they can withstand high temperatures. They can be used as supports or insulators for heating elements in electric heating […]
Introduction In the ever-evolving field of contemporary medicine, the convergence of technology and healthcare has led to remarkable advancements. Among these innovations, radiopaque marker bands stand out as crucial yet often overlooked components that significantly transform the domain of medical imaging. These seemingly simple bands, which may go unnoticed by those unfamiliar with their function, […]
The primary feature of superelastic (SE) Nitinol is its remarkable flexibility, being 10 to 20 times more flexible than stainless steel. This allows the material to “spring back” at strains of up to 11%. Such inherent flexibility is crucial for specific superficial stent applications, particularly in the carotid and femoral arteries, where external pressures can […]
Tungsten copper alloy combines the advantages of metal tungsten and copper. Tungsten has a high melting point (tungsten melting point is 3410℃, copper melting point is 1080℃), high density (tungsten density is 19.34g/cm3, copper density is 8.89 g/cm3); copper has excellent electrical and thermal conductivity, tungsten copper alloy (composition generally ranges from WCu7~WCu50) has uniform […]
According to statistics, 16% to 20% of the total titanium is used in sports and leisure products, which is the third largest titanium application. In terms of sports equipment, titanium is used in: golf clubs, club heads, tennis rackets, badminton rackets, fencing protective masks, swords, sprint shoe spikes, mountaineering tools, skis, ski boots, ski poles, […]
When alumina rods are used as bearings, the smooth surface can reduce the friction between the object and the ceramic surface, making the relative movement between the contact surfaces smoother, reducing wear and energy loss. This is especially important for bearing parts that require frequent contact or relative movement, which can extend their service life […]
In the realm of scientific research, **marker bands** denote the distinct bands observable in techniques such as electrophoresis, spectrophotometry, and X-ray diffraction. These bands are essential for identifying specific molecules, elements, or structures and are crucial across various scientific disciplines, including biology, chemistry, and physics. 1. Role of marker bands in biology (1) Protein and […]
Businesses in many industries, including aerospace, marine shipbuilding, and military/defense, rely on titanium forgings for various industrial and production uses. The metal is in high demand primarily because wrought titanium alloys have an excellent strength-to-density ratio and offer significant corrosion resistance. These two characteristics create a durable, reliable material that can function well on land, […]
Tungsten-copper composite materials are two-phase pseudo alloys composed mainly of tungsten and copper elements. They are metal-based composite materials. Due to the large difference in the physical properties of metal copper and tungsten, they cannot be produced by melting and casting, and are generally produced by powder alloy technology. Tungsten-copper alloys have a wide range […]
