Kiln Furniture & Refractories

NEWSIC

The strength of a refractory is determined by the size and quantity of its pores. NEWSIC (high-strength SiC refractory) is a refractory newly developed by NGK that fills the pores of silicon carbide with metallurgical silicon, resulting in porosity that is as close to zero as possible.

SINSIC

SINSIC (silicon nitride-bonded SiC) features excellent thermal stability and thermal conductivity for heat treatment, and helps stabilize and streamline manufacturing processes.

AIRON

This lightweight kiln furniture is the result of a new production method. For furniture of the same shape and size, it achieves a weight reduction of 30% or more compared with conventional products.

Mullite Stable Refractory

Mullite (3Al₂O₃-2SiO₂) is a refractory material formed by bonding aluminum oxide (Al₂O₃) and silicon dioxide (SiO₂) in a ratio of 3:2. It features exceptional thermal shock resistance and is ideal for use in kiln furniture used for ring of electronic ceramics.

Tableware, Sanitaryware

NGK offers a wide range of kiln furniture and refractories for the tableware and sanitaryware fields.

Firing Saggers

We can recommend ideal saggers for your company with optimized material composition and particle size. Sagger lifetimes are extended through the use of Li-unreactive materials and materials with good resistance to thermal shock.

Filter for Molten Aluminum

NGK molten aluminum filter removes foreign substances and other inclusions from molten aluminum in the production process for aluminum rolled products, functioning to improve the quality of aluminum beverage cans, foils, and other products.
