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 High Hardness Boron Carbide Plate Silicon Carbide Sheet B4C SIC Ceramic Block

High Firmness Boron Carbide Plate and Silicon Carbide Sheet (B4C/SiC) are advanced ceramic products made for extreme environments. These plates combine boron carbide’s unequaled solidity with silicon carbide’s thermal stability. Boron carbide (B4C) ranks 3rd in firmness after diamond and cubic boron nitride. It has a Vickers firmness of over 30 GPa. Silicon carbide (SiC) supplies high thermal conductivity (120-200 W/m · K) and maintains strength at temperature levels up to 1600 ° C

. The boron carbide plate supplies exceptional wear resistance. It is excellent for armor systems, unpleasant jet nozzles, and reducing devices. Its reduced density (2.52 g/cm THREE) makes it light-weight for safety applications. The silicon carbide sheet masters high-temperature setups. It stands up to oxidation and thermal shock. Typical usages consist of furnace elements, semiconductor processing components, and mechanical seals.

Both products feature reduced thermal development coefficients. Boron carbide expands at 4.5-5.6 × 10 ⁻⁶/ ° C. Silicon carbide increases at 4.0-4.5 × 10 ⁻⁶/ ° C. This makes certain dimensional stability under fast temperature changes. They resist chemical rust from acids, alkalis, and molten metals. Boron carbide reveals minimal resistance to solid acids. Silicon carbide performs better in alkaline settings.

The ceramic blocks are manufactured via hot pushing or sintering. This achieves near-theoretical thickness (over 98%). Grain size is managed to maximize mechanical properties. Boron carbide plates generally have a flexural toughness of 300-400 MPa. Silicon carbide sheets get to 350-450 MPa. Surface area surfaces can be customized from rough-ground to polished (Ra ≤ 0.4 μm).

Criterion thickness ranges from 5 mm to 50 mm. Sizes vary approximately 500×500 mm for boron carbide and 600×600 mm for silicon carbide. Custom-made measurements are readily available. These ceramics work in industries like aerospace, defense, power, and heavy machinery. They change steels in applications needing reduced weight, greater temperature level limits, or longer service life.

Electrical homes vary. Boron carbide is a semiconductor. Silicon carbide acts as an electric insulator or semiconductor based on doping. Machining calls for ruby devices because of extreme solidity. Pre-drilled or designed elements minimize post-processing expenses. Dealing with precautions stop edge breaking throughout installment. Storage space in dry conditions avoids moisture-related surface area reactions.
