Modified MDF Composites Intended for the Refractory Application

Abstract:

Paper deals with the preparation and characterization of MDF composite based on the strontium-aluminate cement. MDF composites show enhanced mechanical properties, especially flexural strength. Strontium-aluminate cement has got good thermal stability and capabilities at very high temperatures. MDF composites based on strontium-aluminate cement in combination with polyvinylalcohol were prepared by "high shear mixing" method. The prepared samples were subjected to high temperature solid state reaction at various temperatures. Characterization of MDF samples was mainly based on the methods of testing the flexural strength, X-Ray diffraction and thermogravimetry coupled with differential thermal analysis.
