ISO/TS 22298:2024

This document specifies the characteristics of samples of silica with ordered nanopore array (SONA) to be measured in powder form and the industrially available measurement methods used to determine said characteristics. This document provides a sound base for the research, development and commercialization of SONA for various applications. This document excludes silica-gel, fumed silica and chemically modified SONA. NOTE       The pore size of SONA ranges usually from one nanometre to several tens of nanometres.
