The influence of the kind and powder property of mineral filler on reinforcement effect of silicone rubber was approached. As a result, talc, quartz and wollastonite have better reinforcing effect than the others. The size, surface area, shape of mineral powder are important factors which affect its reinforcing effect of silicone rubber, but the crystalline state of mineral powder is not the main element to affect its reinforcing property.展开更多
作者采用材料物理化学的理论观点和方法,研究了 NaCl(OH-)色心晶体的赋色、热处理过程条件与状态的关系,确立了较适宜的赋色、热处理条件,获得了较纯净的浓度较高的 F 心和O^(2-)-F^+。经后续处理得到了较高浓度的(F_2^+)_H 心,在国内...作者采用材料物理化学的理论观点和方法,研究了 NaCl(OH-)色心晶体的赋色、热处理过程条件与状态的关系,确立了较适宜的赋色、热处理条件,获得了较纯净的浓度较高的 F 心和O^(2-)-F^+。经后续处理得到了较高浓度的(F_2^+)_H 心,在国内首次成功地实现 NaCl(OH^-):(F_2^+)_H色心激光运转。展开更多
文摘The size, surface area, shape, crystallinity of mineral powders and the mechanical properties of silicone rubber composites filled with mineral powders were measured respectively. The influence of the kind and powder property of mineral filler on reinforcement effect of silicone rubber was approached. As a result, talc, quartz and wollastonite have better reinforcing effect than the others. The size, surface area, shape of mineral powder are important factors which affect its reinforcing effect of silicone rubber, but the crystalline state of mineral powder is not the main element to affect its reinforcing property.
