Refractory Products for the Electrical Ceramics Industry

Vulcan Refractories supplies high-performance refractory ceramics and kiln furniture for the electrical ceramics industry. Our materials perform under extreme temperatures, supporting reliable and consistent firing of precision components such as substrates, titanates, ferrites, electrical powders, spark plugs, and electro-porcelains.

Electrical ceramics require tight temperature control and material stability throughout the firing process. Vulcan manufactures its products in the UK to meet the demanding thermal, mechanical, and dimensional requirements of these critical applications.

Applications

Our refractory materials and kiln furniture are used extensively in the production of electrical ceramics and technical ceramics, providing the strength and stability needed for repeated firing cycles. Typical applications include:

• Batts, trays, saggars, setters, props, and spacers for electrical ceramic firing
• Refractory components for the production of substrates, ferrites, titanates, and electro-porcelains
• Custom linings for furnaces and kilns used in the manufacture of electrical ceramics

Each component is manufactured to withstand intense thermal loads and corrosive firing atmospheres while maintaining consistent performance over time.

Products

Vulcan manufactures a range of high-purity refractory products designed for the electrical ceramics industry, including:

• High-purity fused mullite and high-alumina refractories for kiln furniture and support systems
• Sandwich tiles (mullite-coated silicon carbide) used in ferrite production for improved heat distribution and surface quality
• Custom refractory linings for kilns and furnaces, designed to enhance thermal uniformity and energy efficiency

All products are available in standard or bespoke shapes, produced to precise client specifications.

Key Characteristics and Features

Our electrical ceramics refractories are built to perform in extreme operating environments, offering:

• Very high purity and low free silica content to ensure clean, contamination-free firing
• Temperature resistance up to 1750°C for long service life under repeated thermal cycling
• Excellent high-temperature creep resistance and strength retention
• Tight dimensional tolerances for stable firing and consistent product quality
• Smooth surface finishes and flexible shape capabilities for precise process control
• Manufactured in the UK, our refractory ceramics combine performance, reliability, and durability, supporting manufacturers in achieving consistent product output and reduced downtime.
