ASTM C1031-11

Standard Specification for Nuclear-Grade Aluminum Oxide Powder

ABSTRACT
This specification provides the chemical and physical properties and requirements for nuclear-grade aluminum oxide powder intended for fabrication into shapes for nuclear applications. The materials shall conform to physical requirements as to particle size distribution, and specific surface area, and chemical requirements as to loss-on-ignition, and total and elemental concentrations of all impurities. Impurities may include silicaon, iron-chromium-nickel, magnesium, sodium, calcium, hafnium, fluorine, fluorine-chlorine-iodine-bromine, gadolinium, samarium, europium, and dysprosium.
SCOPE
1.1 This specification provides the chemical and physical requirements for nuclear-grade aluminum oxide powder intended for fabrication into shapes for nuclear applications. Two specific uses for which this powder is intended are Al2O3 pellets and Al2O 3 − B4C composite pellets for use as thermal insulator or burnable neutron absorbers, respectively.
1.2 The material described herein shall be particulate in nature.
