Introduction of Boron Carbide Ceramics

Boron carbide ceramics is an inorganic, non-metallic material with carbon and boron as its main components, and its chemical formula is B4C. Since its discovery in the early 20th century, this material has attracted a great deal of attention because of its unique physical and chemical properties. Boron carbide ceramics have an extremely high hardness, second only to diamond and cubic boron nitride, which makes it important in the field of wear-resistant materials. It also exhibits excellent corrosion resistance, high-temperature stability and low-density properties, attributes that make it ideal for the manufacture of bullet-proof vests, nozzles, bearings and other mechanical components that require high wear resistance. Boron carbide ceramics can also be prepared in a variety of shapes and sizes through different processes to meet the needs of different industries.

Characteristics of Boron Carbide Ceramics

Boron carbide ceramics are known for their excellent performance characteristics, starting with their ultra-high hardness and strength, which makes them resistant to severe abrasion and scratching, making them ideal for use in cutting tools and abrasives. Secondly, the material possesses excellent chemical stability and is less likely to react with chemicals such as acids and alkalis, even in extreme environments, making it widely used in certain key components in the chemical industry. In addition, the superior thermal stability of boron carbide ceramics and their ability to maintain structural and property stability at extremely high temperatures makes them one of the key materials in the aerospace and nuclear industries. Finally, it is worth mentioning its lightweight properties, which, due to its low density, make boron carbide ceramics an ideal option for application scenarios that require light weight but high strength. Together, these characteristics give boron carbide ceramics a wide range of applications.

Specification of Customized Boron Carbide Ceramic B4C Circle with Double Holes

This product is a customized boron carbide (B4C) ceramic circle featuring two precision-drilled holes. It is designed for industrial applications requiring extreme durability, wear resistance, and high-temperature stability. The material composition is 99% pure boron carbide, ensuring exceptional hardness (second only to diamond) and lightweight properties. The standard diameter ranges from 10 mm to 500 mm, with thickness options between 3 mm and 50 mm. Hole sizes are adjustable based on customer needs, typically from 1 mm to 30 mm in diameter. Positioning of the holes follows exact client specifications for alignment in assembly processes.

The manufacturing process uses hot pressing or sintering to achieve dense, low-porosity structures. This enhances mechanical strength and resistance to abrasive environments. Surface finishes can be polished to Ra 0.2 μm or left as-machined for specific friction requirements. Tolerances for dimensions are tight, within ±0.05 mm for diameters and ±0.02 mm for hole placements.

Boron carbide’s properties make it ideal for wear parts, armor systems, and neutron absorption components. The double-hole design allows secure mounting in machinery, nozzles, or protective panels. It performs reliably in temperatures up to 2200°C in inert atmospheres and resists corrosion from acids, alkalis, and molten metals. Electrical insulation properties prevent current leakage in high-voltage setups.

Customization includes non-standard sizes, asymmetrical hole arrangements, and secondary processing like chamfering or threading. Material certificates confirm composition and density (2.52 g/cm³). Testing reports cover hardness (HV 30-35 GPa) and fracture toughness (2.5-3.5 MPa·m¹/²).

Packaging uses shock-absorbent materials to prevent transit damage. Lead times vary from 2-6 weeks depending on order complexity. Bulk orders receive discounted pricing. Technical support assists with design optimization for specific load, thermal, or impact conditions.

Quality control includes ultrasonic testing for internal flaws and coordinate measuring machines (CMM) for dimensional accuracy. X-ray fluorescence (XRF) verifies material purity. Each unit is inspected before shipment.

5 FAQs of Customized Boron Carbide Ceramic B4C Circle with Double Holes

What is a Customized Boron Carbide Ceramic B4C Circle with Double Holes?
This product is a high-performance ceramic component made from boron carbide (B4C). It is shaped like a circle and has two holes designed based on specific requirements. Boron carbide is known for extreme hardness, wear resistance, and ability to withstand harsh environments. The double holes allow easy integration into mechanical systems requiring precise alignment or mounting.

What industries use these ceramic circles?
They are used in industries needing durable, heat-resistant materials. Examples include defense (body armor, vehicle armor), aerospace (nozzles, shielding), industrial machinery (wear-resistant parts), and nuclear energy (control rods, radiation shielding). The double-hole design suits applications needing secure fastening or fluid flow.

Can the size and hole placement be customized?
Yes. Dimensions like diameter, thickness, and hole positions are adjustable. Customers provide specifications for hole spacing, diameter, or angle. The goal is to ensure compatibility with existing systems. Customization requires detailed drawings or digital models to guarantee accuracy.

How does boron carbide compare to other ceramics?
Boron carbide is harder than most ceramics, including alumina and silicon carbide. It offers better resistance to abrasion and high temperatures. Its low density makes it ideal for lightweight applications. Boron carbide is brittle compared to metals, so proper handling and installation are critical to avoid cracks.

What are the limits of these ceramic circles?
Boron carbide has high hardness but low fracture toughness. Sudden impacts or uneven stress may cause breakage. Operating temperatures above 500°C in oxidizing environments can degrade performance. Machining after sintering is difficult, so precise shaping must happen during production. Costs are higher than standard ceramics due to complex processing.
