Molecular FormulaSiO2
Confirm the supplied silica form before selecting an industrial filler grade. This silicon dioxide powder has stated purity of 99.5% and the named grades 325-90, 325-92 and 325-95 for technical enquiries, with paint, coating and rubber among the intended applications.
Establish the silica phase for the project
Ask whether the proposed material is quartz-derived or another silica form, and obtain product-specific identity evidence. Review that evidence with the safety information before treating different silica descriptions as interchangeable. The chemical formula SiO2 does not by itself define the physical phase needed by your process.
Read the 325-series names as identifiers
The names 325-90, 325-92 and 325-95 need their own technical specifications. They do not establish mesh values or separate assay percentages. Request the particle distribution, impurity limits and relevant methods for the exact grade being proposed, then confirm how the stated purity applies to it.
- Coating or rubber assessment
- Identify the actual formulation and the filler criteria to be tested.
- Electronics or IC-packaging enquiry
- Request separate phase, impurity and application-qualification evidence.
Decide suitability from a defined sample
Obtain matched technical and safety documents and keep the sample identity with its analysis and trial record. Compare the candidate under conditions relevant to the chosen system before accepting a processing or reinforcement benefit. An industrial filler description does not establish electronics-grade suitability, and a phase-specific recommendation needs evidence for the material actually offered.
