Can I read Cryolite, natural and artificial — Preparation and storage of test samples on EtoBox?
Cryolite, natural and artificial — Preparation and storage of test samples by ISO/TC 226 Materials for the production of primary aluminium is a reference work available to read on EtoBox.
What is Cryolite, natural and artificial — Preparation and storage of test samples about?
Specifies the procedure for the preparation of crude samples and dried samples and of natural and synthetic materials having a molar ratio sodium fluoride/aluminium trifluoride between 3 and 1,7 approximately. The crude sample is intended for the determination of geometric characteristics, for certain physical and physico-chemical tests and for moisture determination. The dried sample serves especially for chemical tests. The principle of the procedure consists in grinding followed by sieving of the sample until the whole passes through a sieve of mesh aperture 0,125 mm. Thorough mixing and drying at approximately 110 °C.
Who reads Cryolite, natural and artificial — Preparation and storage of test samples?
It is typically read by working professionals who need an authoritative practice reference.
Common subject areas: medicine, law, business, engineering.
