Product Classifications and Summaries

Zirconium Oxide and Alumina composition ceramic and refractory products from Zircoa are classified and briefly described below. Summaries include a representative product photo, links to detailed information, as well as both USA Worldwide and European contacts for each product.

Specialty Refractory Products

Specialty Refractory products are typically porous and rough-looking, and are often used in environments where thermal shock resistance is important.

Bricks for Insulation and Glass Contact — Designed for the building of structures without mortar. Ideal for high temperature cycling environments. Eliminates line of sight radiation, and adds physical stability to the structure. (www.zircoa.com/bricks)

Burner Blocks — For quartz melting to high-temperature sintering, with furnace temperatures reaching 2200°C (4000°F) or more. Delivering superior performance, in almost any environment. (www.zircoa.com/burnerblocks)

Zirconia Crucibles — Depending on your application, one of our three different zirconia compositions will mean cleaner melts and castings, with heat-up and cool-down schedules that keep your foundry productive. (www.zircoa.com/crucibles)

Alumina Crucibles — Engineered for broad applications, tighter budgets, repeatable performance and a service limit of 1700° C. Hydraulically pressed, resulting in a uniform surface as well as precise, consistent, dimensional control from one order to the next. (www.zircoa.com/crucibles)

Slidegate Plates — Zirconia can provide the durability and corrosion resistance that is needed to maximize refractory life for the toughest of steel grades. (www.zircoa.com/slidegates)

Coarse Grain Tubes — Either pressed or cast, used primarily in induction heating applications. We manufacture tubes to satisfy the unique requirements of your application. (www.zircoa.com/tubes)

Tundish Metering Nozzles — Numerous compositions and a wide range of shapes are available to maximize steel casting production. (www.zircoa.com/nozzles)

Technical Ceramic Products

Technical Ceramics are extremely dense, very smooth, impervious and wear resistant, developed to solve a wide range of requirements.

Components - Engineered Ceramics — Zycron® compositions L and H were developed to solve a wide range of material requirements. These include environments requiring strength and resistance to corrosion, impact, and high temperature. Their unique properties make them resistant to fracture stress and able to withstand the harshest liquid and gaseous environment. (www.zircoa.com/components)

Mill Mates® Plus™ Dispersion Media — Ceria Stabilized TZP technology. Formulated for a finer, better controlled microstructure, extreme wear resistance, lower mill wear and increased milling efficiencies. (www.zircoa.com/millmates)

Zirbeads™ Dispersion Media — Extremely hard, uniform in size and shape, non-porous, chip and fracture resistant and exceptionally smooth. They are chemically inert, corrosion-resistant, non-conductive and non-magnetic. (www.zircoa.com/zirbeads)

Ceramic Extrusion Dies — Used successfully with both direct and indirect presses. When properly used they will reduce machine shop rework and consistently out-perform traditional tool steel, stellite and high strength nickel alloy dies. (www.zircoa.com/dies)

Grinding Media — Grinding for electronic ceramics, zircon and zirconia, as well as newer electronics markets, which demand higher purity and much less contamination. (www.zircoa.com/grinding)

Granular Products

Granular Products, including Thermal Barrier Coatings, satisfy a spectrum of environmental and performance characteristics, ranging from basic to exotic.

A Grain Zirconia — Zircoa A Grain Zirconia (ZrO₂) is a high purity zirconia produced from zircon sand. Mean particle size is 2-3 microns by Microtrac. Applications include: ceramic color, opacifiers, refractories, catalysts, sensors, electronic ceramics, wear resistant products, zirconium metal production and high temperature insulation. (www.zircoa.com/agrain)

Custom Granular Zirconia (Grog) — Granular zirconia has many applications including firing media, refractory batch formulation, and product filler. Zircoa can provide custom zirconia granules in sizes from aggregate to sub-micron. (www.zircoa.com/grog)

Plasma Spray Powders — These thermal barrier coatings show superior deposition efficiencies and flow characteristics in both internal and external powder feed plasma gun. (www.zircoa.com/spray.powders)

Setter Sands for Electronics — Used for the bulk firing of multilayer ceramic capacitors and other electronic ceramics. Our standard sizing is Tyler mesh -48 + 100. Alternate and custom sizing are available. (www.zircoa.com/setter.sand)
