AluChem was founded in 1978 in Cincinnati, Ohio by Ron Zapletal, Ron Bell and Edward Butera, who still own the company today. The original facility continues to operate in a manufacturing capacity and serves as the corporate headquarters for AluChem, Inc., which operates facilities in Jackson, Ohio and Little Rock, Arkansas.
AluChem started as a specialty Hydrated Alumina (ATH) producer on the supply fundamentals of quality and service, and carried that focus forward as it navigated a strategic plan of investment in infrastructure, expansion and growth. AluChem moved away from Hydrated Alumina several years ago and transitioned into a full complement of specialty aluminas, including Calcined and Tabular Alumina, and Reactive and Polishing grades. Our primary product focus is in the investment casting, refractories, advanced ceramics and polishing industries.
The AluChem team is dedicated to our ownership’s unyielding commitment to producing the highest quality, most tightly controlled products in our industry. This commitment is the driving force behind everything we do. It is why we have moved toward a new line of low and ultra-low soda aluminas focused towards investment casting and ceramics applications. This new high purity product portfolio utilizes proprietary technology in the soda reduction process to produce some of the highest purity aluminas available today.
Our quality. Our service. Our people. Your Solution.
AluChem launched this green initiative in 2008 as a program designed to promote the use of renewable and recyclable materials. Through this initiative, AluChem has utilized more than 6,000 tons of our by-products and solid waste streams in various products, applications and markets. Additionally, we are committed to helping our customers re-purpose their alumina-based, solid waste streams in an effort to reduce cost(s) and avoid landfills.
PRODUCTS
tabular alumina
Tabular aluminas are fully shrunk coarse crystalline alpha aluminas that have been converted to their corundum form. Tabular alumina is produced by sintering ball-formed, intermediately burned calcined alumina at a temperature just under the 2040º C melting point of aluminum oxide. These tabular alumina balls are then crushed, graded or screened, ground and blended to a wide range of granular or powdered particle size distributions. AluChem’s (AC99) tabular alumina is available as low or ultra-low soda, de-ironed and de-dusted and in a wide variety of packages.
The typical properties of tabular alumina are:
• Chemical inertness – resistant to most alkalis and mineral acids
• High-density
• Low water absorption
• Extreme hardness
• High thermal conductivity
• Good resistance to thermal and mechanical shock
• High heat capacity
• High electrical resistance
• Excellent abrasion resistance
Reactive grade aluminas meet the stringent application requirements of advance ceramics and high-quality refractory products, such as castable refractories. AluChem’s reactive grade aluminas are designed for a high-level of performance due to tightly controlled and homogenized particle size distributions developed around high-purity alumina milling components. These finely milled products are controlled to a specific surface area and green density to optimize fired density and provide for controlled shrinkage. Reactive grade products offer excellent sinter reactivity, reduced water demand, and enhance the final product in terms of porosity, wear resistance, mechanical strength and high-temperature mechanical performance.
Calcined alumina is made by firing a source alumina at various temperatures, depending upon desired level of calcination (burn), into alpha alumina varying from 5 – 100% moving it to its densest and most stable form. The calcined alumina particles appear as crystalline agglomerates which are larger when the degree of calcination is higher. Calcined alumina is generally used in the manufacture of refractories, glass and enamel, tile and porcelains and ceramics, including electronic ceramics, etc. AluChem’s calcined family of products are available in unground and ground forms and in various grades based upon: degree of calcination; soda content; and particle size distribution. Typical properties of calcined alumina are:
• High thermal conductivity
• High level of refractoriness
• Chemical inertness
• Wear and abrasion resistance
• Dimensional stability
• High electrical resistivity
• High heat capacity
AluChem offers a wide range of polishing grade aluminas for use in polishing and buffing compounds, abrasives and polishing media. A polishing grade alumina can be applied in various forms, from liquid or solid compounds to slurries or as a dry powder. This product family is specifically designed to achieve various degrees of abrasion/removal and polish/brightness – cut and color. Polishing grade aluminas are offered in both unground and ground forms, characterized by tightly controlled particle size distributions and product consistency/uniformity, derived from aluminas with varying crystal sizes based upon customer needs.
