ABSTRACT:
A pulverable casing (10) includes a housing (12) which is made from a ceramic material and which defines a circular housing closure surface (18). There is a cover (14) on the housing (12). The cover (14) is also made from a ceramic material and defines a circular cover closure surface (20). Cover (14) has a rounded conical exterior surface (24) that defines a skirt angle S of about 120.degree.. The cover closure surface (20) is dimensioned and configured to engage the housing closure surface (18) to define a housing-cover joint (22) which defines a joint angle .alpha. of about 130.degree.. In a particular embodiment, the exterior surface (24) of the cover (14) is rounded to a radius of about 1.8 inches and has a diameter D of about 3.28 inches.
