Study On Preparation And Properties Of Beta Silicon Carbide Advanced Oilstone

Oilstone is an abrasive tool, which is mainly used for processing the mechanical partsand is compared to the “industrial tooth”. There is a great amount of its products inindustry. In China, whetstone manufacturers are spread all over the southeast coastal citiesrepresented by Dongyang, Zhejiang,with low hardness and easy to run out. However，β-SiC, as a new material, that can be used into the oilstone with higher hardness and betterdurability, is expected to become a substitute. As a result，this paper have been studiedthe preparation and physical properties of β-SiC oilstone, including the water absorption,porosity, bulk density and Rockwell hardness.In this paper, physical properties and preparation process of β-SiC oilstone havebeen studied in detail from two aspects of formulation and process, and obtained the bestformula and process under the experimental conditions. Namely:The best formula: when the content of β-SiC is100.0g, potassium feldspar is18.0g,fine naphthalene for6.0g, dextrin as3.0g and30.0g sugar water, B4C for2.5g, kaolin as19.0g.The optimum process: stale time is for1d, molding pressure for30MPa, sinteringtemperature of900℃, and vertical put.The physical properties of self-made whetstone are better than Dongyang whetstoneon the water absorption, porosity, bulk density and Rockwell hardness respectively.
