Spotlighting High-Performance Materials – from Alumina to Zirconia
High-performance materials run the gamut in terms of their composition and properties, but the cutting-edge is occupied by precision-made oxide and non-oxide ceramics. Through decades of innovation, the Saint-Gobain Performance Ceramics & Refractories team has curated a range of market-leading products based on tried-and-trusted chemistries and the latest processing techniques.
This article puts the spotlight on the high-performance materials that we supply to various market segments.
Aluminum Oxide (Al2O3)
Boron Carbide (B4C)
Boron carbide (B4C) is the third hardest high-performance ceramic on earth, exceeded only by cubic boron nitride (cBN) and diamond. B4C ceramics are produced by hot pressing which yields an extremely high-performance boron carbide ceramic with nominal densities of 2.50 grams per cubic centimeter (g/cm3) and a Knoop hardness value of 2,800 kilograms per millimeter squared (kg/mm2).
Chromium Oxide (Cr2O3)
Silicon Carbide (SiC)
Silicon carbide (SiC) is an extremely versatile non-oxide ceramic that performs on multiple fronts for supreme performance in a broad range of application environments. It offers outstanding thermal shock resistance and high-temperature strength as well as intrinsically good mechanical properties for manufacturers in a broad range of markets, from electronics and semiconductors to industrial heating applications.
Silicon Nitride (Si3N4)
Zirconia (ZrO2) is a standout high performance ceramic owing to its unmatched fracture toughness coupled with excellent thermal properties. It is a relatively expensive solution in high-purity formats.
