Carver Uniaxial Press
Location: 2510 GG Brown Connector
Cold Isostatic Press (CIP)
Location: 2510 GG Brown Connector
Cold isostatic pressing can greatly increase the green density of ceramic samples by uniformly applying high pressures (up to 25 Mpa) across samples. The CIP offers flexibility of sample shape along with high pressure compaction of ceramics.
Gel Permeation Chromatograph
Location: 2510 GG Brown Connector
This device uses a column chromatography technique employing as the stationary phase a swollen gel made by polymerizing and cross-linking styrene in the presence of a diluent which is a nonsolvent for the styrene polymer. The polymer to be analyzed is introduced at the top of the column and then is elutriated with a solvent. The polymer molecules diffuse through the gel at rates depending on their molecular size. As they emerge from the bottom of the column they are detected by a differential refractometer from which a molecular size distribution curve is plotted.
Hot Isostatic Press (HIP)
Location: 2510 GG Brown Connector
The simultaneous application of high temperature and pressure provided by the HIP can vastly reduce porosity in ceramic materials. The HIP can compress polycrystalline ceramics to very high densities (>99% of theoretical density) by the elimination of microporosity and internal voids through a combination of plastic deformation, creep, and diffusion.

Lindberg Blue Burnout Furnaces
Location: 2510 GG Brown Connector
MTI GSLI 600X Sintering Furnace
Location: 2510 GG Brown Connector
Micromeritics ASAP 2020
Location: 2510 GG Brown Connector
The ASAP 2020 (Accelerated Surface Area and Porosimetry System) provides versatility in gas selection and high vacuum for high-resolution low surface area measurements. It utilizes the principle of physical adsorption to obtain adsorption and desorption isotherms and information about the surface area and porosity of a solid material. It performs surface area analyses plus pore size and pore volume distributions, typically using nitrogen as the standard gas. It calculates BET and Langmuir surface areas, average and total pore volume, BJH pore size distribution and performs micro-pore analysis. It employs a range of standard theories for the calculation such as Horvath-Kawazoe, Dubinin-Radushkevich, Dubinin-Astakov, t-plot, MP-method, BET, Langmuir and Density Functional Theory.
TA SDT 2960 Simultaneous DSC-TGA
Location: 2510 GG Brown Connector
DTA (Differential Thermal Analysis) measures heat flow to or from a sample as a function of temperature and time. The heat flow and temperature of the sample are monitored in comparison to the reference material. The amount of energy absorbed (endotherm) or evolved (exotherm) as the sample undergoes physical or chemical changes (eg melting, crystallization, curing) is measured in calories as a function of the temperature change. Any material reactions involving changes in heat capacity (eg glass transition) are also detected. TGA (Thermo Gravimetric Analysis) measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principal uses include measurement of a material's thermal stability and composition. It is useful for characterizing polymers, organic or inorganic chemicals, metals or other common classes of materials Weight changes observed at specific temperatures correlate to volatilization of sample components, decomposition, oxidation / reduction reactions, or other changes. The DTA is performed simultaneously with TGA.

Vacuum Ovens (2)
Location: 2510 GG Brown Connector
In vacuum ovens, the heat-treating process takes place inside a vessel that is airtight. This allows a vacuum to be drawn inside the vessel. The entire heat-treating process can take place under vacuum or precisely controlled atmospheres can be introduced. Heat treating under vacuum can: prevent surface reactions, such as oxidation or decarburization; remove surface contaminants such as oxide films and residual traces of lubricants; add a substance to the surface layers of the work; remove dissolved contaminating substances from metals by means of degassing. Ovens are built of several kinds of high temperature (refractory) materials to hold the process material and hold in the heat without breaking down during the several months that they usually run. Ovens are lower temperature (usually
