leveraging the power of silicon carbide ceramic plates in modern technology

Silicon carbide ceramic is one of the hardest and most durable advanced ceramic materials, with excellent resistance against corrosion, high temperatures, acids and physical wear.This material can be found in oil and gas production sand filters as well as mechanical seal parts found on pumps, forgings and rocket engines. Furthermore, it can also be found in industrial furnace refractory linings as refractory heating elements.

High-temperature resistant

Silicon carbide has long been one of the most sought-after materials in modern technology due to its diverse properties. Notably, its hardness and wear resistance are very high while it can also be formed into any desired form. Furthermore, silicon carbide’s thermal expansion coefficient is relatively low which makes it stable even under extreme environmental conditions. Silicone rubber is an essential material in the automotive, mechanical and chemical industries as well as environmental protection, space technology and information electronics applications. Furthermore, it can also be used for advanced refractory materials and abrasives, and serves as an excellent material choice for ballistic armor applications. Silicon carbide armor material stands out as it offers high hardness and can absorb large amounts of energy without shattering. Furthermore, its extremely high melting point allows it to fuse with steel into composite armor bodies. Production methods for silicon carbide include either reaction bonding or sintering processes. Production methods dictate the microstructure and properties of any material created through reaction bonding, including its strength. Reaction bonding involves infiltrating compacts made up of SiC and carbon with liquid silicon before heating it to form compacts that then need to be bonded together. Reacting with carbon to form more silicon, this reacts with initial SiC particles to bond them together further and complete sintering, similar to production of metals but using non-oxide sintering aids instead. Both methods produce high quality silicon carbide with high flexural strength and thermal shock resistance.

Silicon carbide sintering processes can be carried out under high pressure, which allows the ceramic to maintain its integrity at high temperatures without suffering degradation in physical properties or becoming susceptible to acid, alkali or other chemicals, while still remaining machineable into various shapes and sizes. Furthermore, these materials can withstand extreme temperatures while remaining resistant against acid or alkaline solutions and chemicals.

Silicon carbide can be machined into complex shapes with high accuracy using CNC mills, though care must be taken when handling the material due to shrinkage during sintering; accordingly, handling must be handled carefully so as to minimize damage – this is particularly essential when working green or biscuit silicon carbide prior to sintering.


Silicon carbide ceramic plates have numerous applications in modern technology. This material is an inorganic non-oxide ceramic with superior hardness, wear resistance, thermal expansion and chemical stability properties; making it an exceptional refractory choice for use in furnaces and kilns. Aluminum oxide (AOx) can also be found as an abrasive in various applications, including sandpaper and grinding wheels, thanks to its distinctive atomic structure which gives it its extraordinary properties. Composed of silicon (Si) and carbon atoms with either hexagonal or cubic crystal structures. As a semi-conductor it features a wide band gap; further improved through doping processes by inserting impurities into its lattice which change its electrical characteristics.

Ceramic SiC plate heat exchangers boast outstanding corrosion and abrasion resistance, being resistant to nearly all acid and alkali mixtures even at elevated process temperatures. This makes them the ideal solution for separating corrosive liquids from carrier gases and condensing vapours sensitive to metallic surfaces.

Advanced silicon carbide boasts a Moh’s hardness of 9.5 and five times stronger than nitride-bonded ceramic, making it a formidable alternative to traditional alumina materials. Not only is its service life five to seven times greater, it is much more resistant to oxidation, sliding abrasion resistance, and has superior sliding abrasion resistance than its alumina counterparts.

These plates are constructed using a mixture of SiSiC powder that has been sintered into dense forms using dry pressing techniques in an inert atmosphere, creating thick plates ranging in thicknesses between 8mm and 45mm.

Boron is added to SiC matrix during its production to increase tensile strength and hardness, creating a lightweight yet strong ceramic material with unparalleled ballistic protection against modern weapons and threats. These ceramic materials form the core component of Saint-Gobain Performance Ceramics & Refractories’ next-generation of ballistic armor systems.


Silicon carbide ceramic plates are extremely hard, making them resistant to abrasion and impact, with good corrosion resistance at operating at higher temperatures. Because of these properties, silicon carbide ceramic plates make ideal materials for wear protection in industrial settings, including conveyors, pumps and turbines – as well as heat exchangers in chemical engineering processes.

Tetrahedral crystals make this material much harder to break than conventional refractory materials, as well as more resistant to abrasion, thermal shock and fatigue. Furthermore, its low thermal expansion rates make it an excellent choice for high temperature applications like those found at IPS. Incorporating this material has brought numerous wear-resistant and corrosion-resistant products which utilize it.

Reaction bonded silicon carbide, commonly referred to as RSIC or SISIC, is an ideal wear-resistant material for conveying coarse particles, classification, concentration and dehydration processes, welding/socketing capabilities and smooth surface that prevent scale/dust buildup. Furthermore, RSIC/SISIC’s excellent chemical stability at higher temperatures makes it well suited for separating corrosive gas mixtures while condensing corrosive vapours into condensation streams.

Silicon carbide stands out from its aluminum-based counterpart with an extremely high melting point and can be utilized in applications that demand superior chemical resistance and strength, such as wafer tray supports in semiconductor furnaces where temperatures of 1600oC can be sustained without loss of strength; resistors and varistors also benefit greatly from using this material.

abrasion resistance of Silicon carbide ceramic depends on the size and distribution of soil particles. Wear rates for nitride-bonded silicon carbide ceramics tend to be 1.36 times greater in light soil compared with medium soil, and 6.5 times greater than in heavy soil due to friction caused by sand grains rubbing against friction surfaces on silicon carbide ceramics, eventually chipping off and leading to premature failure of these ceramics.

Pressureless sintered silicon carbide is an ideal material for wear-resistant ceramic liners due to its combination of high strength and low coefficient of friction. Furthermore, its thermal conductivity properties make it suitable for applications involving extreme temperature conditions like kiln furniture.
