Overview of Silicon Carbide Powder

Silicon carbide (SiC) powder is a high-performance ceramic material composed of silicon and carbon. Known for its exceptional hardness, thermal stability, and wear resistance, SiC powder is widely used in abrasives, cutting tools, refractory materials, and advanced technological applications like semiconductors and electric vehicle components.

Features of Silicon Carbide Powder

Exceptional Hardness: One of the hardest known materials, second only to diamond, making it ideal for abrasive and cutting applications.

Thermal Stability: High resistance to thermal shock and can withstand extreme temperatures, enhancing its utility in refractory and high-temperature environments.

Chemical Inertness: Resistant to most chemicals, including acids and alkalis, ensuring durability in harsh conditions.

Wear Resistance: Excellent wear resistance properties make it suitable for demanding mechanical applications.

Electrical Conductivity: Depending on the purity and doping levels, SiC can exhibit varying degrees of electrical conductivity, useful in electronics.

Technical Specifications for Silicon Carbide (SiC)

Product Overview

Our silicon carbide comes in multiple purity grades: 70%, 83%, 85%, 88%, 90%, and 98% SiC. Each grade meets strict quality standards and suits different industrial needs.

Chemical Composition

The main component is silicon carbide (SiC). Higher percentages mean fewer impurities. The 98% grade contains minimal free carbon and silica. Lower grades like 70% or 83% include more ash, iron, and other elements. Exact composition varies by grade and application.

Physical Properties

Silicon carbide is very hard—close to diamond on the hardness scale. It resists heat well and does not melt easily. Its thermal conductivity stays high even at elevated temperatures. The material also shows strong resistance to wear and corrosion.

Grain Size Options

We offer various grain sizes from coarse to fine. Common mesh ranges include 12/20, 20/40, 60/80, 100, and 200. Custom sizing is available upon request to match your process requirements.

Common Applications

– 70–85% SiC: Used in refractory bricks, foundry facings, and basic abrasives.
– 88–90% SiC: Suitable for advanced refractories, kiln furniture, and metallurgical additives.
– 98% SiC: Ideal for high-performance ceramics, semiconductor components, and precision grinding media.

Packaging and Handling

Products are packed in moisture-proof bags inside sturdy woven polypropylene sacks. Standard weights are 25 kg or 1,000 kg bulk bags. Store in a dry place away from direct contact with water or acids.

Quality Assurance

Every batch undergoes lab testing for SiC content, particle size, and impurity levels. We follow ISO-certified procedures to ensure consistent performance and reliability. Certificates of analysis are provided with each shipment.

Applications of Silicon Carbide (SiC) Across Key Purity Grades

70% SiC – Foundry and Refractory Uses

70% silicon carbide works well in foundries. It boosts thermal conductivity in molds and cores. This grade also strengthens refractory linings in furnaces. Its lower purity keeps costs down while still delivering solid performance in high-heat settings.

83%–85% SiC – Abrasives and Wear Parts

Grades like 83% and 85% SiC are common in abrasive products. They go into grinding wheels, sandpaper, and cutting tools. These levels offer a good mix of hardness and cost. They also serve in wear-resistant parts such as nozzles and liners where moderate purity meets durability needs.

88%–90% SiC – Industrial Ceramics and Metallurgy

At 88% to 90% purity, SiC suits advanced ceramics and metal processing. It helps make kiln furniture that holds shape under stress. In metallurgy, it acts as a deoxidizer and carbon additive in steelmaking. This range balances performance and price for heavy-duty industrial use.

98% SiC – High-Tech and Semiconductor Roles

98% SiC is the top tier for demanding applications. It’s used in semiconductor substrates, LED production, and electric vehicle power devices. This ultra-pure form ensures excellent electrical and thermal properties. It also supports aerospace components and high-frequency electronics where reliability is critical.

5 FAQs of 70%/ 83%/85%/88%/90%/98% SiC Silicon Carbide (producer)

Frequently Asked Questions About Silicon Carbide (SiC) Products

What purity levels do you offer for silicon carbide?

We produce silicon carbide in six standard purity grades: 70%, 83%, 85%, 88%, 90%, and 98% SiC. Each grade meets strict quality control standards for consistent performance.

Which industries use 70% to 85% SiC?

Lower-purity SiC (70%–85%) is mainly used in refractory materials, abrasives, and metallurgy. These grades work well where high hardness and thermal stability are needed but ultra-high purity is not required.

Why choose 88% or 90% SiC?

The 88% and 90% grades offer a balance between cost and performance. They are common in advanced refractories, ceramic parts, and some industrial wear applications. These purities reduce impurities that could affect product reliability.

When is 98% SiC necessary?

98% SiC is used in high-tech fields like semiconductor manufacturing, electric vehicle components, and aerospace. This grade has very low levels of iron, aluminum, and other contaminants, which ensures better electrical and thermal properties.

How do you ensure consistent quality across all grades?

Every batch goes through rigorous testing using XRF and chemical analysis. We control raw materials, furnace conditions, and post-processing steps closely. This gives you stable composition and reliable performance—no matter which purity you select.
