Silicon Nitride Ceramics, also known as Si3N4 ceramic, is a type of advanced ceramic material with high strength and hardness. It is widely used in various industries due to its excellent properties such as high temperature resistance, wear resistance, and corrosion resistance.
Silicon Nitride Ceramics is available in the form of balls, rods, tubes, and custom shapes to meet different application requirements. It is typically used in high-performance applications that require superior mechanical and thermal properties.
A.Compressive Strength: 3800 MPa
B.Color: Black/Gray
C.Bending Strength: 800-1200 MPa
D.Fracture Toughness: 7 MPa
E.Hardness: 14.9GPA
These properties make Silicon Nitride Ceramics highly suitable for demanding applications in industries such as aerospace, automotive, electronics, and medical.
Silicon Nitride Ceramics has a wide range of applications, including:
A.Ball bearings: SI3N4 ceramic balls are commonly used in high-speed and high-load bearing applications due to their high strength and wear resistance.
B.Cutting tools: The high hardness and wear resistance of Silicon Nitride Ceramics make it an ideal material for cutting tools used in machining and metalworking industries.
C.Heat exchangers: SI3N4 ceramic tubes and rods are used in high-temperature applications such as heat exchangers due to their excellent thermal shock resistance and corrosion resistance.
D.Medical implants: The biocompatibility and high strength of Silicon Nitride Ceramics make it a suitable material for medical implants such as dental implants and joint replacements.
E.Transmission device in high temperature equipment Si3N4The excellent high temperature resistance of ceramics makes its strength and hardness almost unchanged at 800°C, while the hardness of bearing steel decreases significantly when it exceeds 120°C.
F.High-speed operation field, high-speed electric spindle bearings, machine tool spindle bearings, dental drill bearings, instrumentation bearings.Si3N4The density of ceramic is3.20g/cm3,Much lower density than bearing steel 7.85g/cm3,Therefore, the ceramic rolling elements can effectively resist the centrifugal force generated by high-speed rotation and reduce the load of the rolling elements. At the same time, the rotation and sliding between the rolling element and the raceway can be reduced, and it has a beneficial effect on preventing surface damage. Ceramic ball bearings do not need to add lubricating grease frequently, and the characteristics of sensitive rotation, fast starting, good inertia and long life are fully reflected.
G.Aviation and aerospace fields Si3N4The coefficient of linear expansion of ceramic is3.2*10-6/K,Almost of bearing steel1/4,and so Si3N4Ceramic bearings are more stable when used in environments where temperature changes. For example, in the ultra-low temperature environment, ceramic materials exhibit excellent performance and are a candidate material for a new generation of hydrogen engine bearings. H.Chemical machinery and equipment, food, marine and other field.Ceramic bearings can solve the corrosion problem. I. High vacuum field Using the self-lubricating properties of Si3N4 ceramics can solve the vacuum pollution caused by the use of lubricating media in steel bearings. J.Strong magnetic field environmentIn a strong magnetic field environment, the metal micropowder worn down by the steel bearing itself is firmly adsorbed between the rolling elements and the raceway surface, which will cause early spalling damage and increased noise of the bearing. The solution is to use ceramic bearings. K.Civil products such as bicycles, roller skates, model airplanes and electric toys L.Ceramic bearings are widely used in bicycles, roller skates, model airplanes and electric toys with their advantages of being lighter, more wear-resistant and faster, and are especially popular among top players in these fields.
The production of Silicon Nitride Ceramics involves several steps, including:
A.Mixing: Silicon Nitride powder is mixed with binders and other additives to form a homogenous mixture.
B.Shaping: The mixture is then shaped into desired forms such as balls, rods, or custom shapes using various techniques such as pressing or extrusion.
C.Sintering: The shaped parts are sintered at high temperatures to form a solid and dense material.
D.Machining: The sintered parts are then machined to achieve precise dimensions and surface finish.
