The tribological properties of zinc borate ultrafine powder as a lubricant additive in sunflower oil
This paper presents an investigation on the tribological properties of zinc borate ultrafine powder (ZBUP) employed as a lubricant additive in sunflower oil. The stable dispersions of 0.5 wt%, 1 wt% and 2 wt% ZBUP in sunflower oil were achieved by using an ultrasonic homogenizer. Both a 4-ball tester and a pin-on-disc tester were employed to evaluate the antiwear and friction reduction capabili...
متن کاملThe preparation and tribological properties of surface modified zinc borate ultrafine powder as a lubricant additive in liquid paraffin
This paper investigates the effects of surface modification of zinc borate ultrafine powders (ZB UFPs) on their tribological properties as lubricant additives in liquid paraffin (LP). ZB UFPs were successfully modified by hexadecyltrimethoxysilane (HDTMOS) and oleic acid (OA). It is evident that HDTMOS modified zinc borate ultrafine powder (HDTMOS-ZB UFP) delivered a small conglomerate size, go...

len, Zinkleerstellen oder CL-Ionen) die grüne Lumineszenz bei kleineren Konzentrationen nicht ausgeschlossen werden, es tritt aber gleichzeitig die langwellige Bande mit steigender Aktivatorkonzentration immer mehr hervor. Das heißt aber, daß nur ein Teil der vielleicht vorgegebenen Zinkleerstellen durch Indium besetzt wird. — Da die orange-rote Emission mit Indium und Kupfer schon bei kleinen ...
متن کاملPotassium zinc borate, KZnB3O6
The title compound, KZnB(3)O(6) contains a remarkable [B(6)O(12)](6-) group ( symmetry) formed by two rings linked by edge-sharing BO(4) tetra-hedra, a feature that has only been observed previously under high pressure conditions. These borate groups are connected through distorted ZnO(4) tetra-hedra in edge-shared pairs ( symmetry), forming a three-dimensional network whose cavities are filled...
متن کاملLaZnB5O10, the first lanthanum zinc borate
Lanthanum zinc penta-borate, LaZnB(5)O(10), was synthesized by flux-supported solid-state reaction. It is a member of the LnMB(5)O(10) (Ln = rare earth ion and M = divalent metal ion) structure type. The crystal shows a three-dimensional structure constructed from two-dimensional {[B(5)O(10)](5-)}(n) layers with the lanthanum (coordination number nine) and zinc (coordination number six) ions fi...
