Introduction

The Inamori School of Engineering at Alfred University is a leading educational institution in the United States for ceramic and glass engineering and science. Approximately 40% of all ceramics engineers in the United States have degrees from Alfred University. It is host to the Scholes Library, which is unique in the world in being dedicated to ceramics and art. Many other significant resources are available at Alfred University.

Biomaterials Facilities

The biomaterials facility includes two laboratories.

The first is the high temperature furnace lab which has two high temperature furnaces and a microwave furnace. There is also gyromills which are used for grinding the glass made in the furnaces.

The actual biomaterials lab includes three autoclaves used for sterilizing materials/instruments. There is a water de-ionizer to remove all minerals/contaminants from the water: important in biological work. The lab also has various incubators/ovens for storage and aging of samples and a centrifuge for separating solids/cells suspended in a solution. Included is a laser profilometer to image and determine the surface texture and roughness of materials surfaces in the main bio labs. There is a class II fume hood used extensively for cell culture, and also for culturing bacteria and yeast. There are various microscopes in the lab, the best being a digital Olympus optical microscope which we can use to monitor cell growth and also use to measure the size of objects such a pores in materials. A particle size analyzer is used to determine the mean particle size distribution of materials. A vi-cell coulter counter measures the viability of cells after exposure to materials. Included also are a Uv/vis spectrometer and a 96 well plate reader. A -80 freezer is used to store bacteria and fungi cultures and a CO2 incubator for growing mammalian cells.

Ceramic Processing

The KISoE boasts one of the best equipped laboratories for ceramic powder processing research. In addition to a communition equipment (jaw crusher, roller mill, ball mills, speed mills, vibratory mills (both wet and dry), attrition mills, and automated mortar and pestles) the school maintains a complete array of powder and rheological characterization instrumentation (see Powder and Suspension Characterization), slurry processing equipment (high intensity mixer, low-speed high-torque mixers, and filter pressing capabilities for large and small volumes), spray dryer, forming equipment, and two pilot plant facilities (one for traditional ceramics and one for dielectric ceramics), heat treatment and sintering equipment (see Furnace and Sintering Capabilities), and mechanical and electrical testing instrumentation (see Mechanical and Electrical Characterization). The facilities can accommodate aqueous and non-aqueous processing; wet, dry, and semi-dry processing, including slip casting, tape casting (a laboratory bench scale model and a controlled environment pilot plant scale model), injection molding, extrusion (both auger and piston extrusion with vacuum de-airing capabilities), and dry pressing (manual and automatic with an 80-ton biaxial dry press).

Powder and Suspension Characterization

Powder characterization capabilities range from standard sieve analysis (via Ro-tap), laser and x-ray particle size analysis, surface area (N2-BET), He-pycnometry and other pycnometer methods (aqueous and non-aqueous via pycnometer bottles), zeta-potential (direct observation via laser, acoustophoretic mobility, and streaming potential), potentiometric titration with a sample changer, and porosimetry (via N2 and Hg). Image analysis is also possible via optical and scanning electron microscopy.

A complete array of equipment is available for rheology measurements, including Brookfield and Gallenkamp viscometers, stress- and strain-controlled rheometers, and DMA (Dynamic Mechanical Analysis). The stress- and strain-controlled rheometers can also perform small amplitude oscillatory measurements for viscoelasticity characterization using a range of geometries (parallel plate, cone and plate, and concentric cylinder). Also, unique to these facilities is a high pressure shear rheometer (designed and built at Alfred University) for measuring plasticity of plastic bodies and evaluating shear behavior of low water content bodies at high pressure.

Furnace and Sintering Capabilities

Ceramic samples can be dried and sintered in a broad array of furnaces and kilns. For sintering in air, the capabilities encompass electric resistance heating at low temperature (Kanthal wire kilns with a maximum temperature of 1100°C), intermediate temperature (SiC heating elements; 1500°C maximum), and high temperature (1800°C via MoSi2), a gradient furnace (1450°C maximum, and several gas-fired furnaces that range in temperature from 1400°C to 1950°C (with oxygen assist). For inert atmosphere (either vacuum or argon) four furnaces maintained here have either tungsten (2000°C maximum) or carbon (2300°C maximum) heating elements. Three of these are small sample sizes (3x3x6cm) and one larger capacity furnace (30x30x30cm).

Coating Facilities

Thin film coating facilities include an ion-assisted electron beam deposition system with planetary substrate rotation assembly, RF/DC/pulsed-DC sputtering system and RF aerosol mist deposition system.  The first two systems are vacuum systems, and the last system is a non-vacuum system.  Coating materials include silicon nitride, iron nitride, aluminum nitride, aluminum oxide, cerium oxide, indium tin oxide, titanium oxide, etc.  The substrate shapes include plate, curved, and tube shapes among others. The substrate sizes vary from 9” to a fraction of an inch.

Nanomaterials Pilot Plant

The new NYSTAR-sponsored Center for Prototype Manufacturing of Nanostructured Electroceramics (a.k.a. “Pilot Plant”) is a partnership between the Center for Advanced Ceramic Technology (CACT) at Alfred University and the Center for Advanced Materials Processing (CAMP) at Clarkson University. Researchers have developed pilot plant facilities and expertise for the synthesis of nano-sized ceramic powders, from which will be manufactured specific electronic components and devices for consolidation into nano-structured electroceramic components with enhanced properties, such as multi-layer capacitors, zinc-oxide varistors, solid oxide fuel cells and ferrite inductor cores. Collaborations are planned with regional industrial partners and entrepreneurs to develop and transfer technology, spurring innovation and economic development. A class-10,000 clean-room facility located at the Ceramic Corridor Innovation Center is for critical electro-ceramic device fabrication techniques including tape casting, screen printing, lamination, die-pressing, and isostatic pressing. Innovative firing techniques in addition to conventional fast-fire processing such as microwave sintering will be used to retain the nano-structure. Researchers with CAMP at Clarkson University design and produce novel process intensification reactors for pilot scale synthesis of nano-particles. CAMP will use these techniques to increase production capacity of particles known to have application in advanced electronic materials but now available in only small quantities. The intensified modular plant will be capable of delivering pilot-scale throughput of up to 1 kg / dry powder per day and will be adaptable to different types of chemical synthesis. Once the nano-powders have been prepared, they will be sent to Alfred for further processing into electroceramic devices.
