Glass ceramic 9606. This novel material has been classified by nasa as a glass ceramic and is produced by controlled crystallization. Glass ceramic materials were first developed at the corning glass works and share properties of both the parent glass material and polycrystalline materials. After about 30 years of informal use as a standard in high heat 1000 c applications pyroceram 9606 was approved by nist as a certified reference material for thermal conductivity measurements. High strength high elastic modulus and uniform dielectric properties.

Pyroceram 9606 was certified as a reference standard after being used informally for over 30 years in high temperature applications that demand working at temperatures of about 1000 c 1832 f. Naval radiological defense laboratory measured its thermal diffusivity. Glass ceramic materials share many properties with both glasses and ceramics glass ceramics have an amorphous phase and one or more crystalline phases and are produced by a so called controlled crystallization in contrast to a spontaneous crystallization which is usually not wanted in. In this article we look at how they differ from glass materials how they are produced some typical compositions and their applications.

Pyroceram can be manufactured in ogival pointed arch shapes hemispheres pressware sheets and various machined shapes. Corning pyroceram code 9606 glass ceramic categories. Cristobalite although present in the x ray diffraction. Within advanced optics there are three main products that are available at an industrial scale.

The microstructure of a cordierite glass ceramic corning code 9606 is depicted in fig. Pyroceram is a heat resistant glass ceramic that can tolerate exceptionally high temperatures. Since its creation manufacturers have extended the use of pyroceram to commercial ovens broilers heat insulators anti. Glass ceramics are polycrystalline materials produced through controlled crystallization of base glass.

Results of mechanical testing for pyroceram tm glass ceramic mechanical testing for pyroceram trademark 9606 glass ceramic fabricated by corning was conducted to determine mechanical properties of the material including slow crack growth valid testing was not achieved in tension compression and shear testing due to inappropriate test specimen configurations provided and primarily due to. The predominant phase with somewhat rounded grains is cordierite. Pyroceram was first implemented to create casserole dishes and saucepans. In actuality it is a transparent version of ceramic.

The sharp angled needle shaped crystals have been identified as magnesium aluminum titanate or a pseudobrookite solid solution. Pyroceram was originally a proprietary brand name. In the early 1960s the national bureau of standards nbs measured the thermal diffusivity and the thermal conductivity of that material and the u s. Some of those are thermal shock resistance heat insulation high strength toughness high temperature stability and isolation capabilities to name a few.
