Choosing the wrong particle size range for black silicon carbide processing can leave surface finish Ra values 8 to 15 times above specification. This guide maps FEPA macro and micro grit grades to achievable Ra ranges, explains the physical mechanisms behind each transition, and gives engineers a practical framework for selecting the right grade from first principles.
Boron carbide delivers Vickers hardness of 2,900–3,580 HV combined with 85–92% visible transmittance, making it a technically superior choice over DLC and TiN for scratch-resistant coatings on optical elements and display glass. This article covers deposition methods, adhesion interlayer design, powder purity specifications, and the standardised test protocols that govern acceptance in optical and display supply chains.
Green silicon carbide outperforms alternative abrasives on cemented carbide grinding due to its 2,480 HV hardness, controlled semi-friable fracture pattern, and purity above 99.0% SiC. This guide covers grit selection, bond system specification, thermal management, and the cost boundary where diamond wheels become preferable over GC for WC-Co tool grinding.
Fused calcium aluminate in self-flowing castables delivers measurably better flow, hot strength, and sulfur resistance than sintered grades in petrochemical furnace linings. This article explains the phase chemistry behind those gains, presents comparative performance data across key ISO test standards, and outlines the specification and sourcing criteria engineers need to qualify the material for critical applications.
Choosing between white and brown fused alumina for blasting comes down to four variables: substrate chemistry, anchor profile target, recycling economics, and downstream process sensitivity. This guide compares hardness, friability, iron content, and cost-per-cycle, with a decision matrix and PO checklist to specify the right grade with confidence.
Selecting between fused calcium aluminate and lime-alumina briquettes in ladle metallurgy involves more than unit cost — dissolution kinetics, hydrogen pickup risk, inclusion control, and refractory wear all differ significantly between the two. This technical comparison gives steel process engineers the data needed to justify the right flux choice for their grade and refining route.
Black silicon carbide delivers intrinsic thermal conductivity of 100–120 W/m·K, making it one of the most cost-effective fillers for thermally conductive compounds. This article presents loading-level data, particle size effects, electrical resistivity trade-offs, and formulation guidance engineers need to specify SiC-filled heat sink materials with confidence.
Back-surface texturing of monocrystalline and multicrystalline silicon wafers demands an abrasive capable of precise, uniform micro-pit formation without introducing sub-surface lattice damage that degrades minority
Green silicon carbide does not degrade chemically at ambient conditions, but surface oxidation, grit compaction, and fine-grade agglomeration can measurably reduce bond adhesion and particle size consistency within 90 days under poor storage conditions. This article presents controlled trial data and practical protocols to protect specification compliance across the full inventory cycle.
Black SiC is suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive.
