GB/T 23807-2009精細陶瓷分類系統

本標準規定了精細陶瓷的分類。該系統包括陶瓷粉料前驅體、粉末、陶粒、纖維、晶須、片晶、單晶、多晶、非晶態(玻璃)材料，及復合材料、陶瓷薄膜、涂層。該分類系統將構成標準的核心。分類系統不包含以下：a 碳材料，除某些特殊陶瓷如金剛石、玻璃碳或者化學氣相沉積石墨以外；b 硅材料，鍺元素以及其他半金屬材料，但它們作為精細陶瓷組成或前驅體時除外；c 粘土類傳統陶瓷，包括：1 日用陶器(餐具等日用精細陶瓷制品)；2 建筑衛生陶瓷；3 墻體材料；d 定形的和不定形的耐火材料。本標準適用于精細陶瓷的分類。本標準不適用于硬質合金產品或者主要成分為玻璃的制品，但可以參照采用。本標準不是為了強制規范該分類系統如何使用，而是提供一個靈活框架和一個推薦性的可操作的編碼系統，使用人員可以根據陶瓷產品信息編訂編碼。

ASTM C750-1989(1997)核級碳化硼粉末標準規范

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.
