熱傳導性優異之固形狀金屬。亦可於糊狀金屬粒子組成物 之加熱時施加壓力。此時,可使揮發性分散媒⑻或揮發 性分散媒⑹揮散’接著燒結金屬粒子(a)彼此,亦可使揮 發性分散媒⑻或揮發性分㈣⑹揮散,㈣燒結金屬粒 子(A)彼此。尤其在金屬粒子(A)為銀粒子之情況,由於銀 原本便具有高強度與極高電傳導性及熱傳導性,因此,本 毛月之銀粒子彼此的燒結物亦具冑高強度與極高電傳導 性及熱傳導性。此時之加熱溫度只要為使揮發性分散媒⑻ 或揮毛生刀政媒(C)揮散而銀粒子可燒結之溫度即可,通 常為loot以上,尤以15(TC以上為佳。然而,若超過4〇〇 °C,則揮發性分散媒會以突彿方式蒸發,可能對固形狀金 屬之形狀造成不良影響,因此必須在4〇(rc以下,較佳為 300°C以下。僅利用加熱不易燒結之金屬粒子(A),亦藉由 一邊加壓並施加超音波振動,或者一邊加壓、加熱並施加 超音波振動,而可良好地燒結。 超音波振動之頻率為2kHz以上,i〇kHz以上為佳。其 上限並無特別限制,以裝置能力而言大約為5〇〇kHz。又, 312XP/發明說明書(補件)/96-07/96109691 19 200822991 超:波振動之振幅會影響燒結性,因此較佳為0. 1〜40//m, 更仏為0.3 20//m,尤佳為〇·5〜。另外,為了使超 音波振動確實傳達至糊狀金屬粒子組成物,較佳係將超音 波振動之發射部分直接抵接於 糊狀金屬粒子組成物。或 者透過不易吸收超音波振動之素材所構成之覆蓋材等, 將超音波振動之發射部分抵接。對糊狀金屬粒子組成物之 抵接疋力’較佳為〇· 9kPa(0. 09gf/mm2)以上,更佳為 9kPa(j· 92gf/_2)以上,尤佳為 39kpa(3· 98gf/_2)以上,

The above-mentioned pieces of the second quilt: plus ^ (the reagents sold by Wako Pure Chemical Industries Co., Ltd. plus eight 15, ethylene glycol as a volatile dispersion medium (c) 吏:; | electric coefficient 39. 0) The rotary kneading machine is uniformly mixed, and the composition of the paste silver particles is prepared by the 312XP/invention specification (supplement)/96-07/96109691 27 200822991. Eight:: Silver: The composition of the sub-component is not observed in the syringe. The adhesion strength between the silver particles and the composition of the paste-like silver particles is observed. The results of the above-mentioned ir-ir silver particles are known to be silver-free particles. It is separated from the dispersion and has excellent preservation stability, and is useful for strong viscous δ metal members. [Example 8] 4η fragmented copper particles were obtained by fragmenting commercially available copper particles, and the average particle diameter of the primary particles was measured by a laser diffraction method) (the copper surface was coated with 0.5 weight (four) of stearic acid, The copper particles have water repellency), and 15 parts of glycerin is added to the above-mentioned fragmented copper particles (the reagent of the company sold by Wako Pure Chemical Industries, Ltd., and the dielectric coefficient of 47 0) is used as a volatile component. The rotary kneading machine is hooked to mix 'by this to modulate the composition of the paste copper particles. The paste copper particle composition did not observe separation of the copper particle disk dispersion medium in the syringe. The results are shown in Table 2. As a result of the above, it is understood that the paste copper particle composition does not have separation between the copper particles and the dispersion medium, and is excellent in storage stability for a long period of time. [Example 9] In Example 8, except for the substitution of copper particles, fragments obtained by fragmenting commercially available recording particles to produce primary particles having an average particle diameter of 6 Mm (measured by a laser diffraction method) were used. A paste nickel particle composition was prepared in the same manner as in Example 8 except that the nickel particles were coated with 8 wt% of oleic acid and the nickel particles were water-repellent. The paste nickel particle composition was not isolated in the syringe. 312 ΧΡ / invention specification (supplement) / 96-07/96109691 28 200822991 The separation of nickel particles I was observed. The results are shown in Table 2. It is known from the + σ fruit that the paste-like nickel particle composition does not have nickel particles and a dispersing medium, and is excellent in storage stability for a long period of time. [Example 1 〇 ] ', 00 00 wounds are commercially available by precipitation method, and the average particle size of the secondary particles ><Ten body shot method; the granular silver particles (the silver surface is covered with 8% of the stearic acid, the silver particles have water repellency), and the N'N~methylmethanamine is added (Wako Pure Chemical Industries Co., Ltd. = test reagent 'dielectric coefficient 38.0) As a volatile dispersing medium (C), the mash-type and the east machine were uniformly mixed to prepare a paste-like silver particle composition. The adhesion of the silver particles and the knife of the paste to the composition of the paste silver particles was not observed in the syringe of the eight-paste silver particle composition, and the relationship i σ was not in Table 2. From the above results, it is understood that the composition of the paste silver particles is not separated from the dispersion medium by the silver particles. The storage stability is excellent, and it is useful for strongly bonding metal members. [Example 11] In Example 1, except for the substitution of the phenol, 15 parts of pure water (dielectric coefficient 80. 0) was used as the volatile dispersion medium (10), and ethanol was used instead of the hexahydrate (Wako Pure Chemical Industries Co., Ltd.)

A mixture of 15 parts of pure water and 3 parts of ethanol has a dielectric constant of 68. The paste silver particle composition was not observed to separate the silver particles from the dispersion medium in the syringe. The results of measuring the adhesion strength of the silver-reduced particle composition are shown in Table 2. From the above results, it is known that the 312XP/invention specification (supplement)/96-07/96109691 29 200822991 shed-shaped silk fabric has no filament and excellent resolution, and is useful for strongly bonding metal members.
