本實驗使用不同粒徑的綠色碳化矽粉末，以固定比例10 wt%聚乙烯醇縮丁醛(PVB)作為孔洞生成劑和黏結劑，添加不同比例的高嶺土原礦做為燒結助劑，並以酒精作為介質來製備多微孔性碳化系陶瓷。燒結時以Al2O3粉末覆蓋坯體，置於高溫爐中，以1300℃持溫3小時，成功在常壓下製備多微孔性碳化矽陶瓷。
研究中PVB先與SiC粉末混合均勻研磨造粒，再加入高嶺土粉末繼續研磨混合均勻，過100目篩，再以單軸加壓50 MPa，可得生胚，將坯體埋入Al2O3粉末中，以500℃燒除PVB生成孔洞後，再加溫至1300℃持溫3小時，得到不同之碳化矽燒結體。燒結體藉由XRD分析主要晶相及二次相成分及數量，以SEM觀察燒結體表面顯微結構、孔洞大小以及連通情況，以阿基米得法求得燒結體視密度及開放性孔洞率，以萬能試驗機測得燒結體抗壓強度，並以熱傳導分析儀量測試片熱傳導值。
研究結果顯示在1300℃持溫3小時的燒結環境下，其開放性孔洞率與燒結體視密度成同步變化的趨勢，以試片6S5K開放性孔洞率26.6％為最高值，其視密度為1.678g/cm3。

The study was putting different quantities of Kaolinite and 10 wt% PVB into six different kinds of particle of powder to produce the micro porous SiC ceramic. We used the binder / pore former PVB, which is 10 wt%，and Kaolinite was add to be the sintering aid. The bulk is covered with Al2O3 in the heating furnace while sintering, we heat at 1300℃ and hold 3 hours. We have then produces the micro porous SiC ceramic successfully within a low constant temperature.
At first, we added the PVB and mixed it with the powder of SiC. After drying, we ground it into a powder, and then added Kaolinite as the sintering aid. After pass through 100 mesh, the powder was uniaxially pressed at 50 MPa and the result was green bodies. Cover up the green bodies with Al2O3 powder, burn out the PVB to form pores by 500 ℃, sinter them and heat the temperature to 1300℃ for 3 hours. Therefore, the result was different SiC sintered bodies. We used XRD to identify the produced phase and SEM to observe the fractured surfaces to discover the grain morphology of sintered bodies. By using the Archimedes, we got the apparent density and open pore. We got the compressive strength by the Material Test System as well.
The research showed that ： under the condition of sintering at 1300 ℃ for 3 hours, the open pore and the Apparent Density are showing that there is a trend in synchronized variation. They had the same trend in the synchronized variation. The open pore is 26.6 % of the sample of 6S5K is the highest rate. Its Apparent Density is 1.678g/cm3 。
