Spray-Dried Ceramic and Glass Powders
 GBC's
ceramic powders are ready to form by tablet
pressing or isostatic pressing methods.
Precise ball milling and spray-drying
enables GBC to provide highly flowable
and homogeneous powder characteristics.
GBC offers matched and compression sealing
glasses prepared for dry pressing. Many
standard industrial sealing glasses from
major manufacturers are available as well
as custom-milled and blended formulations.
GBC's laboratory facilities provide accurate
shrinkage and density data with each lot
of material. All powders are supplied
in standard minus 40-mesh or graded to
our customer's needs. The powders can
also be "lubed" upon request,
or lubricants and binders can be recommended
to solve specific pressing and firing
problems.
GBC powders are available in minimum lots
of 5 pounds.
