About National Ceramic
National Ceramic Company makes high quality custom ceramic products. Our objective is to supply your ceramic needs no matter what the application. Staffed by professionals, NCC provides custom ceramic production expertise with the capability to handle your project from concept through completion.
National Ceramic Company can produce very precise components, but also standard tolerance, cost effective components depending on the specific application need. Low tooling costs, particularly for small and prototype quantities, are often possible as a result of our production methods.
We specialize in small to medium volume production runs, but we also have the capability to take prototype and small experimental and startup projects to large quantity production.

Material Information
STEATITE
L3 Steatite - Good electrical properties, temperature capabilities to 1800° F, and high strength. A good choice for applications requiring good electrical insulation but not involving high frequency.
L5 Steatite - Good electrical properties at normal and radio frequencies, high strength, and ability to withstand temperatures to 1800° F. Applications include coil forms and other insulators in radio frequency applications, and a wide range of electrical insulators where good electrical and mechanical properties are required.
C10 Steatite - Our high thermal expansion body developed to facilitate ceramic glass to metal sealing while retaining the good electrical and mechanical characteristics of our other steatite bodies.
CORDIERITE
Porous, with a low coefficient of thermal expansion and the ability to withstand thermal shock and temperatures to 2200° F. this is an excellent choice for applications such as element hangers and spacers in ovens and kilns, part holders for heat processing in relatively clean and dry environment, and electrical insulators applications such as gas ignition, again in relatively clean and dry environments.
Vitrified, with the most of the properties of the porous cordierite, but without the porosity. These characteristics make this material very useful where absorption would be a problem, such as oil ignition. It is easier to keep clean than the porous cordierite.
ALUMINA
We manufacture alumina components in four grades of purity: 92%, 95%, 96%, and 99.5% to meet a wide range of needs. All have good electrical and mechanical characteristics, are able to withstand elevated temperatures exceeding 2500° F, and have good wear properties. Applications include thread and wire guides, spark plugs and ignition devices welding and sand blast nozzles, and electrical insulators in furnaces and ovens, including high vacuum applications.BPSR Information
