例２
ニッケル：ポリマー成分の体積比が約５０：１に対応する、
ALFAS IndustriesのＲＴＶシリコーン・タイプ１０００ ６ｇ
ＩＮＣＯニッケル粉２８７ ３０ｇ
を用いて、例１の手順を繰り返した。その比は例１より低いが、用いられたシリコーンのグレードの架橋における特性収縮は、印加圧力なしで粒体を電気的伝導性とした。その収縮は、架橋における揮発性成分の減量の所産であると思われる。ＡＬＦＡＳ１０００は、１２質量％（重量％）の揮発性物質を含む（ＡＬＦＡＳ２０００は、４質量％（重量％）の揮発性物質を含む）。
Example 2
Nickel: volume ratio of the polymer component is about 50: the corresponding to 1,
ALFAS Industries RTV Silicone Type 1000 6g
INCO nickel powder 287 30g
And the procedure of Example 1 was repeated. Although the ratio is lower than in Example 1, the characteristic shrinkage in the crosslinking of the silicone grade used makes the granules electrically conductive without applied pressure. The shrinkage appears to be the result of a loss of volatile components in the crosslink. ALFAS 1000 contains 12% by weight (% by weight) of volatiles (ALFAS 2000 contains 4% by weight (% by weight) of volatiles).
