- A Study on Bloating of Porous Ceramic
- Abstract
- The study on bloating of porous ceramic was proceeded. The porous ceramic is made by using powdered basalt sludge and the characteristics on bloating casued by addition of clay, glass powder and CaCO3 are investigated.
The clay helps to combine powdered basalt sludge, added from 0wt% to 20wt% and the soda glass helps bloating of specimen by forming glass phase on the surface of specimen, added 0wt%, 50wt% and 100wt%. The blowing agent CaCO3 is a component forming molten phase, added 0wt%, 5wt%, and 10wt%.
The specimens were rapidly heated in furnace at 1,100, 1,150, and 1,200℃ for 15min, respectively, to sinter porous ceramic.
Clay belongs to bloating range of Riley can not discover forming glass phase on surface of specimen at 1,200℃. But the specimen made up of 100wt% clay was rapidly heated, as a result, the black core was discovered within the specimen.
Powdered basalt sludge does not belong to bloating range of Riley. But glass phase of high viscosity on surface of specimen formed owing to addition of glass powder.
As a result, porous ceramic is made by blocking emission of gas generated within the specimen.
The chemical composition of materials were determined, and characteristics were analyzed, including specific gravity, water absorption.
The porous ceramic which is heated at 1,200℃ has specific gravity of 0.53g/㎤, water absorption of 3.08%, and this value is satisfied with KS L 8551 standard.
