HEAT-STORAGE MATERIAL AND SOLAR ENERGY TRANSFORMER BASED THEREON |
摘要 |
FIELD: heat-storage materials. ^ SUBSTANCE: invention relates to mixtures capable of accumulating heat energy and relevant solar energy transformers. Heat-storage material according to invention contains silicon dioxide, 3-5% of liquid soda glass, and 50-82% of VO2+x wherein x=0-0.5. Material is prepared by compacting mixture of vanadium dioxide VO2+x and silica in presence of liquid soda glass as binder followed by solidification at 150-200°C. Summary heat when using combined transformer including phase transformation heat (alpha-VO2 <-> beta-VO2) and oxygen adsorption-desorption heat of mechano-chemically treated VO2+x may reach 250 J/g. ^ EFFECT: increased heat-storage capacity. ^ 8 cl, 1 tbl |
