Das bei diesen Versuchen verwendete amorphe Antimontrisulfid wurde hergestellt durch Fällung,
indem Schwefelwasserstoff zu einer wässerigen Lösung von Antimontrichlorid zugeführt wurde. Die so hergestellten
Sulfide waren ziegelrot und hatten vor dem Schmelzen im Vergleich zu kristallinen Antimonsulfiden
ein verhältnismäßig niedriges spezifisches Gewicht. Die modifizierten Schmierfette wurden hergestellt

Zugabe des Antimontrisulfids und/oder des Bleinaphthenats in Form eines Ölschlammes.

Es wurden Schmierfette hergestellt durch Vermählen eines hydrophoben, oleophilen Ammoniumtones und
eines Schmieröls mit einer Viskosität von 55 Sec. SSU bei 99 0C zwecks Herstellung eines Schmierfettes mit
einem Ammoniumtongehalt von 6,18%. Dieses Schmierfett entsprach nicht dem Timken-Test bei
9,1 kg Druck. Es versagte auch beim Timken-Test mit 9,1 kg Druck bei Anwesenheit von Antimontrisulfid.
Die Modifizierung des letztgenannten Schmierfettes mit Hilfe von 0,4% Calciumcarbonat erhöhte die
Timken-Zahl auf 13,6 kg, während eine Erhöhung des Calciumcarbonats auf 1% die Timken-Zahl auf
22,7 kg erhöhte.
