Study the Changes of Bending Specification Strength at Adding Glass Powder to Iraqi Kaolin

Abstract

Recently the needs to certain types of ceramic products with specific properties in the industry and general public uses or especially for high-performance computing systems, the scientist go to the nature to obtain many types of these materials ecologically save, less processing mining, low cost, cheap, low efforts, and in sometimes with high industrial specifications. Because of the growing interest on environmental issues, this work carried out using the clay present naturally in Iraq to promote a sustainable processing of such materials, as bending resistant and mechanical properties. The results of this work refer that the highest value for bending resistant was 16.5 MPa. when the ratio was 20% glass powder / 80% kaolin; while the lowest value was 9.1 MPa. when the ratio was 0% glass powder / 100% kaolin; 11.5 MPa when the ratio was 10% glass powder / 90% kaolin; 16.5 MPa when the ratio was 20% glass powder / 80 % kaolin and finally 11.52 MPa when the ratio was 30% glass powder / 70% kaolin. This work shows that the best bending strengths obtained were 16.5 MPa when blending 20% glass powder / 80% Kaolin to manufacturing glass-ceramics; melting the mixed powder ?1150^oC, this results give us the best limitations in such types of ceramic industry which decrease the production cost, time, efforts in the same time obtained a good best products quality in scientific and general public uses.
