ASTM C750-03
Historical Standard: ASTM C750-03 Standard Specification for Nuclear-Grade Boron Carbide Powder
SUPERSEDED (see Active link, below)
ASTM C750
1. Scope
1.1 This specification defines the chemical and physical requirements for boron carbide powder intended for a variety of nuclear applications. Because each application has a different need for impurity and boron requirements, three different chemical compositions of powder are specified. In using this specification, it is necessary to dictate which type of powder is intended to be used. In general, the intended applications for the various powder types are as follows:
1.1.1 Type 1 -For use as particulate material in nuclear reactor core applications.
1.1.2 Type 2 -Powder that will be further processed into a fabricated shape for use in a nuclear reactor core or used in non-core applications when the powder directly or indirectly may cause adverse effects on structural components, such as halide stress corrosion of stainless steel.
1.1.3 Type 3 -Powder that will be used for non-core applications or special in-core applications.
