Latest Patents

David A Bell's latest patents focus on the creation of advanced refractory articles. One patent describes a process for making a filter suitable for filtering molten metal. This process involves forming a slurry that includes particles of refractory material, a binder, and a liquid carrier. The method includes several steps: coating a disposable former with the slurry, drying the coated former, optionally applying additional coats of refractory material and/or binder, and finally firing the coated former to produce the filter. The binder used is a carbon-rich source selected from materials such as pitches, tars, and organic polymers that degrade to form carbon upon pyrolysis. Another patent details a filter for molten metal, which is an open-pored porous material made from refractory particles embedded in a carbon matrix bonding material. This filter can be produced by forming a porous article from refractory particles and a carbon-rich binder, followed by firing to generate the carbon matrix.
