Bearing Materials | AST Bearings
Metallurgical Growth will cause a change in dimension and form of any steel parts such as bearings'' even at room temperature. While not a problem with low precision commodity type bearings, in high precision (ABEC 5P, 7P, 9P) miniature bearings this lack of dimensional stability can cause problems.

Creep and thermal behavior of quarry dust-silicon …
Abstract In this research, creep and thermal behavior of stir cast ZA-27 alloy-based hybrid composites modified with quarry dust (QD) and silicon carbide (SiC p) particles was investigated.ZA-27 hybrid composite samples reinforced with 10 wt% QD-SiC p particles containing varied weight percentage 0, 25, 50, 75, and 100% quarry dust was developed using stir casting technique.
Bearing Steel - an overview | ScienceDirect Topics
Silicon nitride has some higher performances than bearing steel in the appliion of high temperature, high speed, corrosive environment, under vacuum and no lubricants. However, most of ceramic bearings are rolling bearings and there has been no precedent for ceramic spherical sliding bearing.

Silicon carbide (SiC) is an important ceramic nonoxide material used in mechanical engineering, because of the unique set of properties: low density, high hardness, high-temperature strength and high chemical resistance . For many years, the silicon carbide
Tin (Sn) Powder - Nanografi Nano Technology
Tin is a chemical element with the syol Sn and atomic nuer 50. Tin is a post-transition metal in group 14 of the periodic elements. It is obtained chiefly from the mineral cassiterite, which contains stannic oxide, SnO2. Tin is the 49th most abundant element on Earth and has, with 10 stable isotopes, the largest nuer of stable isotopes in the periodic table,
