| The objective of this research is to study the effect of Percentage on apparent porosity and compressive strength of ceramic filters. In this research, using ceramic raw materials to produced the filters. Filters made from the raw materials (Sand, Kaolin, and Calcium Carbonate), which obtained from Um Urdhuma and Al- Deuechla in the west of Iraq. Sand was the basic material used to make filters. Selective some of sand particle size (150µm, 125µm, 100µm, 75µm, 50µm), In addition to the binder material that consisted (65% Kaolin + 35% Calcium Carbonate), in different weight percentage (60% Binder + 40% Sand, 50% Binder + 50% Sand, 40% Binder + 60% Sand) ), and used the semidry compaction to forming the laboratory samples The samples dried in (110 ºC) for (24 hours), and fired or sintered at 1200ºC for soaking time (1hour),then we extracted compressive strength and apparent porosity. The experimental result led to the relationships between (rate of sand, particle size of sand) and apparent porosity and compressive strength of ceramic filter. . Increased the rate of sand increased apparent porosity, but it decreased compressive strength. ). Increased particle size of sand decreased apparent porosity, but it increased compressive strength. The rustles show the maximum apparent porosity (41.328%) at the maximum weight percentage of sand (60%)), and minimum particle size of sand (50µm).The highest compressive strength( 11.831MPa) at lowest weight percentage of sand (40%), and maximum particle size of sand (150µm) . | ||
