Gel Casting of Parts from VK94-1 Ceramic
摘要
Abstract
Castings based on a ceramic suspension containing 80 wt % VK94-1 powder were produced using the gel casting method. A gel-forming agent system based on acrylamide (the main monomer) and methylene bisacrylamide (the crosslinking monomer) was used. The sintered ceramic is characterized by a fine crystalline structure with a grain size of 2–8 μm and a uniform distribution of glass phase layers, with a relative density of up to 93% and an ultimate bending strength of up to 332 MPa.
