    Abstract: PURPOSE:To enable the production of high-dense sintered products from an ultrafinely pulverized ZrB2 of not so high purity, by adding an organosilicon compound, which can be converted mainly into SiC by pyrolysis, to a ZrB2 forming the mixture, and firing under normal pressure. CONSTITUTION:ZrB2 is pulverized to less than 10mu particle sizes. The ZrB2 powder is combined with an organosilicon compound which can be converted into mainly SiC by pyrolysis. The organosilicon compound has the main skeleton mainly composed of Si and C atoms and the side-chains almost of which are converted into amorphous products or fine particles over 600 deg.C. The amount of the silicon compound is preferably about 5-40wt.% based on the ZrB2 powder. The mixture is formed, gradually burned in an inert atmosphere up to 500 deg.C to remove plasticizers or such and sintered at about 2,000-2,200 deg.C under normal pressure.

    Abstract: PURPOSE:To prepare a harmful exhaust gas removing agent of high collecting speed without a large-scale humidying device by using an alkaline earth metal compound containing water as an effective component. CONSTITUTION:Water is added to an alkaline earth metal compound such as calcium hydroxide powder or the like, and after granulating, the same is dried and dried compound is calcined to prepare a lump of removing agent. Water content is absorbed to said removing agent by introducing nitrogen gas containing steam. The harmful exhaust gas removing agent thus prepared is filled into a column, and the exhaust gas containing gaseous harmful component like silane, diborane, hydrogen selenide or the like is flowed through. The gaseous harmful component is collected by the alkaline earth metal compound dissolved in the water content.
