The summary obtained as follows : (1) The temperature has an important effect upon this reaction. The main reaction between 1100 and 1200℃ takes place by the following equation. CaCN_2 + MgO -> Mg + CaO + C + N_2 At 1200 ~ 1250℃ the following reaction must be postulated theoritically, 2CaCN_2 + MgO -> Mg + CaO + CaC_2 + 2N_2 But according to our experiments, the pyrolysis of calcium cyanamide predominates above reaction. (2) The yield of magnesium per unit charge shows a maximum at CaCN_2/MgO = 1.25 ~ 1.5 (mol ratio) below 1250℃. (3) The addition of calcium fluoride about l0% (weight) increases the yield of magnesium (4) Calcium cyanamide as a reducing reagent gives a higher yield of magnesium than calcium carbide.}, pages = {93--103}, title = {酸化マグネシウムとカルシウムアナミドとの反応}, volume = {9}, year = {1966} }
