Title (EN) FILLER POWDER AND METHOD FOR PRODUCING SAME
(FR) POUDRE DE CHARGE ET PROCÉDÉ DE PRODUCTION DE CELLE-CI
(JA) フィラー粉末及びその製造方法
Abstract:
(EN) Provided is a filler powder that has a thermal expansion coefficient lower than that of silica powder and with which a resin composition having excellent light transmittance can be obtained. The filler powder comprises crystallized glass formed by precipitating a β-quartz solid solution and/or β-eucryptite and is characterized in that the ratio D90/D10 of the diameter on cumulative 90% (D90) to the diameter on cumulative 10% (D10) according to a laser diffraction scattering particle size distribution measurement is 20 or less.
(FR) L'invention concerne une poudre de charge ayant un coefficient de dilatation thermique inférieur à celui de la poudre de silice et avec laquelle une composition de résine ayant un excellent facteur de transmission de la lumière peut être obtenue. La poudre de charge comprend du verre cristallisé formé par précipitation d'une solution solide de β-quartz et/ou de β-eucryptite et est caractérisée en ce que le rapport D90/D10 du diamètre sur 90 % cumulatif (D90) au diamètre sur 10 % cumulatif (D10) selon une mesure de distribution de taille de particule de diffusion par diffraction laser est de 20 ou moins.
(JA) シリカ粉末よりも熱膨張係数が低く、かつ、光透過率に優れた樹脂組成物を得ることが可能なフィラー粉末を提供する。 β-石英固溶体及び/又はβ-ユークリプタイトを析出してなる結晶化ガラスからなるフィラー粉末であって、レーザー回折散乱式粒度分布測定による累積10%粒子径(D10)と累積90%粒子径(D90)との比D90/D10が20以下であることを特徴とするフィラー粉末。
