- Product Introduction
Products Description
Black Silicon Carbide (SiC) - High-Performance Refractory Material Solution
Black Silicon Carbide is an industrial abrasive and refractory material manufactured through high-temperature smelting of premium raw materials - primarily quartz sand and petroleum coke - in specialized electric resistance furnaces. Known for its exceptional hardness, it ranks just below diamond, making it a superior choice for demanding industrial environments.
This material features a unique combination of physical properties: sharp and brittle grain structure, notable thermal conductivity, and adequate electrical conductivity. These characteristics make it suitable for a wide range of applications, including surface preparation (sanding, grinding, polishing), specialized abrasive tools such as grinding wheels and sandpaper, as well as industrial uses in anti-slip flooring, precision casting, and high-grade refractory aggregates.
Key Advantages for Refractory Applications:
Outstanding thermal stability under high temperatures
Excellent thermal conductivity for efficient heat management
Superior wear and abrasion resistance
Low thermal expansion coefficient ensuring dimensional stability
Reliable electrical insulation properties
Compared to green silicon carbide, Black Silicon Carbide offers higher toughness, making it the preferred abrasive for processing materials with low tensile strength. It is widely used in treating glass, ceramics, natural stone, various non-ferrous metals, cast iron, and especially in monolithic refractories and high-temperature linings.
Ideal for manufacturers and suppliers in the refractory industry, our Black SiC ensures enhanced durability, thermal shock resistance, and prolonged service life in extreme operating conditions.
