A solenoid air pump is a type of air pump that uses a solenoid to control the flow of air. Solenoid air pumps are commonly used in a variety of applications, such as aquariums, medical equipment, and industrial automation. They are known for their reliability, efficiency, and low noise levels.
Overall, solenoid air pumps are a versatile and reliable type of air pump that can be used in a variety of applications. Their ability to control the flow of air makes them ideal for situations where precision and accuracy are important.

There are several types of solenoid air pumps, including diaphragm pump, Piston Pump, and rotary vane pump. Mini Diaphragm Pump is the most common type of solenoid air pump and are used in a wide range of applications. They use a flexible diaphragm to move air in and out of the pump, creating a vacuum.
Piston pumps use a piston to move air in and out of the pump, while rotary vane pumps use a rotating vane to move air. Both of these types of pumps are typically used in more heavy-duty applications, such as industrial automation and manufacturing.
Cubic silicon carbide, also known as β-SiC, is a material belonging to the cubic crystal system, similar to the diamond structure. It has an impressive hardness on the Mohs scale, ranging from 9.25 to 9.6, which is very close to that of diamond. This makes it highly suitable for applications requiring extreme durability and wear resistance. Compared to white corundum and α-SiC (black and green silicon carbide), β-SiC offers superior finish and polishing performance, making it ideal for high-precision manufacturing.
At temperatures above 1600°C, β-SiC retains its ultra-high strength and excellent resistance to creep and fracture, making it a reliable material in high-temperature environments. As a semiconductor, it exhibits much higher conductivity than α-SiC. Additionally, β-SiC has excellent thermal conductivity and a low coefficient of thermal expansion, which minimizes thermal stress during heating and cooling cycles. It is a low-temperature crystalline form, and when heated beyond 1800°C, it undergoes a structural transformation into other forms. In terms of density, β-SiC is significantly lighter—about half the density of most alloys and roughly 40% that of steel, comparable to aluminum.
There are three main methods for producing β-SiC: laser synthesis, plasma processing, and solid-phase synthesis. The first two techniques primarily produce nano- and sub-micron powders but often result in lower purity and incomplete particle density due to short reaction times. Solid-phase synthesis is more complex, with many variations, but currently, only one company in Shaanxi, Xikeboer, has achieved consistent high-quality, high-purity, and batch production of β-SiC. Other manufacturers remain at the theoretical or experimental stage, facing challenges such as low β-phase content, impurities, and difficulties in mass production.
β-SiC micropowder possesses remarkable properties, including high chemical stability, exceptional hardness, excellent thermal conductivity, a low thermal expansion coefficient, a wide band gap, high electron drift velocity, and good electron mobility. These characteristics make it ideal for applications in electronics, information technology, precision machining, military, aerospace, advanced refractories, special ceramics, and high-performance grinding materials.
Due to its diamond-like structure, β-SiC particles are spherical and exhibit outstanding wear and corrosion resistance, along with high thermal conductivity and low expansion. These properties make it an excellent candidate for special coatings. When applied to common materials, it significantly enhances their wear resistance. For instance, standard carbon steel drill bits can only drill 1–2 holes before breaking, while those coated with β-SiC perform better than alloy bits, allowing them to drill 20–50 holes. Similarly, aluminum alloy pistons used in engines experience significant wear, but β-SiC coatings can increase their lifespan by up to 30–50 times.
As a precision abrasive, β-SiC outperforms white corundum and α-SiC, offering superior finishing quality. Although it is more expensive than many other abrasives, its performance in various industries is often comparable or even better than diamond. For example, when used for grinding stainless steel, silicon wafers, or glass, β-SiC can achieve a finer finish than diamond at a fraction of the cost.
In the stainless steel grinding industry, white corundum-based oil stones and grinding discs are widely used, but they have limited service life. By contrast, β-SiC-based abrasives provide a higher finish, greater grinding force, and longer life. Replacing white corundum oil stones with β-SiC ones can improve bearing surface finish by 2–3 grades and extend product life by 5–8 times, reducing the frequency of replacements and lowering labor costs. β-SiC is also used in abrasive pastes, polishing liquids, high-precision abrasive cloth belts, and super-abrasive coatings, all of which show great potential in industrial applications.
