Materials Free Full-Text Characterization of Magnesium

Magnesium silicate hydrate (MSH) gel was formed by reacting magnesium oxide (MgO) with silica fume (SF) in distilled water. The MSH was prepared using a MgO/SF molar ratio of 1.0 (40 60 weight ratio). Samples were analyzed during hydration process up to 300 days at room temperature. The MSH characterization has been carried out using a range of analytical techniques.

refractory castable selection and use

Study of spent refractory waste recycling from metal . Feb 01 1999 · Natural and synthetic raw materials are used to create many different refractory products. The selection of a particular product for use as a refractory lining is governed by the temperature and process requirements for each application.

Recycling Practices of Spent MgO-C Refractories

The recycling options of spent MgO-C refractories from an electrical arc furnace (EAF) have been evaluated. The economic quality of spent refractories and products made from it the ease of implementation of a recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a
