Which Industries Use Silicon Carbide 88/90 Grade Most?

Silicon Carbide 88/90 is one of the most widely used grades of metallurgical silicon carbide in high-temperature industrial processes. Due to its balanced SiC content, reduction efficiency, and cost effectiveness, Silicon Carbide 88/90 is heavily used in steelmaking, foundry melting, and refractory production.

ZhenAn supplies stable-quality Silicon Carbide 88/90 for global metallurgical buyers, steel plants, and foundries that require consistent reaction performance and economical furnace additives.

This guide explains exactly which industries use Silicon Carbide 88/90 the most and why this grade is often preferred over higher-purity alternatives.


What Is Silicon Carbide 88/90 Grade?

Silicon Carbide 88/90 (SiC 88/90) is a metallurgical-grade silicon carbide material typically used as a deoxidizer, reducer, and silicon-carbon additive in furnace operations.

Typical specification range:

SiC content: 88–90%

Fixed carbon: process dependent

SiO₂: controlled range

Form: lumps, granules, powder

Application class: metallurgical silicon carbide

Compared with abrasive or ceramic grades, Silicon Carbide 88/90 is optimized for reaction efficiency and furnace economics, not ultra-high purity.

ZhenAn produces Silicon Carbide 88/90 with controlled particle sizing and batch stability suitable for industrial charging systems.


Steelmaking Industry - Primary User of Silicon Carbide 88/90

Steelmaking is the largest consumption sector for Silicon Carbide 88/90.

Main Steel Plant Applications

Silicon Carbide 88/90 is used in:

Electric arc furnace (EAF) operations

Induction furnace steelmaking

Ladle refining

Deoxidation processes

Slag conditioning

Partial ferrosilicon replacement

Why Steel Mills Choose SiC 88/90

Steel producers select Silicon Carbide 88/90 because it provides:

Strong deoxidation capability

Combined silicon and carbon contribution

Good reduction reaction speed

Lower alloy cost per ton of steel

Improved furnace efficiency

For cost-controlled steel production, SiC 88/90 offers a favorable performance-to-price ratio compared with higher SiC grades.


Cast Iron Foundries - High Usage Segment

Iron foundries are another major buyer group for Silicon Carbide 88/90.

Foundry Use Cases

In cast iron melting, Silicon Carbide 88/90 is used for:

Silicon and carbon adjustment

Melt chemistry correction

Furnace charge optimization

Graphite structure support

Melt temperature efficiency

Technical Advantages in Foundry Furnaces

Using Silicon Carbide 88/90 can help:

Enhance nucleation behavior

Improve casting consistency

ZhenAn supplies graded Silicon Carbide 88/90 sized for induction furnace and cupola furnace feeding systems.


Refractory Manufacturing Industry

Refractory producers use Silicon Carbide 88/90 in general-grade high-temperature materials.

Typical Refractory Applications

Refractory bricks

Castables

Furnace linings

Wear-resistant layers

Thermal shock resistant products

Why SiC 88/90 Is Used Here

For many refractory products, Silicon Carbide 88/90 provides:

Heat resistance support

Structural reinforcement

Oxidation resistance contribution

Cost-efficient performance

Higher purity silicon carbide is used for premium refractories, while SiC 88/90 is widely used in industrial-grade refractory production.


Slag Treatment and Metallurgical Service Companies

Metallurgical treatment contractors use Silicon Carbide 88/90 for reaction and efficiency improvement programs.

Common uses include:

Slag modification

Reduction enhancement

Furnace energy optimization

Reaction yield improvement

These buyers typically purchase Silicon Carbide 88/90 in bulk tonnage and focus on reaction value per cost unit.


When Higher SiC Grades Are Preferred Instead

Silicon Carbide 88/90 is not designed for ultra-high purity sectors.

Higher grades are preferred in:

Abrasive production

Precision ceramics

Semiconductor materials

Advanced sintering

Electronic substrates

For these industries, ≥98% silicon carbide grades are required instead of metallurgical SiC 88/90.


How Industrial Buyers Choose Between SiC Grades

Professional buyers usually select silicon carbide grades based on process goals.

Choose Silicon Carbide 88/90 when:

Cost efficiency is critical

Bulk furnace addition is required

Deoxidation and reduction are primary goals

Steelmaking or cast iron melting is the target use

Choose higher SiC grades when:

Purity directly affects product quality

Ceramic or abrasive performance is required

Impurity limits are strict

ZhenAn technical teams support buyers in selecting the correct Silicon Carbide 88/90 size and grade for each furnace type.

FAQ - Silicon Carbide 88/90

Is Silicon Carbide 88/90 good for steel deoxidation?
Yes. Silicon Carbide 88/90 is widely used as a composite deoxidizer and reducer in EAF and induction furnace steelmaking.

Can SiC 88/90 replace ferrosilicon?
It can partially replace ferrosilicon in many steelmaking and foundry processes to reduce alloy cost.

Is Silicon Carbide 88/90 used in aluminum production?
No. Aluminum metallurgy normally uses silicon metal rather than metallurgical silicon carbide.

Does higher SiC percentage always mean better performance?
Not always. Correct grade selection depends on furnace process, reaction goal, and cost model.
