摘要： A novel type of zeolite is obtained by replacing ion-exchangeable active cations in A-type zeolite with potassium ions and divalent cations at 33.3 to 83.3% and 16.7 to 66.7%, respectively to combine into the total of 100%. This zeolite is effective for separation of a mixture consisting of non-polar molecules and polar molecules having the adsorption effective cross-section less than 5 A. For instance, monosilane and phosphine, both of which are adsorbed by the conventional Ca--A type zeolite, can be separated by the novel K--A type zeolite which adsorbs phosphine.

摘要： Diamond crystals are produced by subjecting to elevated temperatures and pressures a mixture of a nondiamond form of carbon together with a mixture or alloy of cobalt and phosphorus, which serves as the solvent and catalyst for the conversion to diamond form. Use of cobalt and phosphorus for solvent and catalyst allows conversion of nondiamond carbon to diamond at lower pressures than previously utilized, i.e., from about 42,200 to about 49,000 atmospheres.
