Title: Production of extremely easily sinterable alumina
Inventor: TAKAHASHI YUKIHIKO
IPC: C01F7/02
Filed: 1992-11-05
Abstract: PURPOSE:To improve the sinterability of alumina by adding seeds to precipitated Al(OH)3: particles, crushing the particles, classifying the crushed particles to separate coarse particles, calcining the fine particles and washing the product. CONSTITUTION:An alkali aluminate is hydrolyzed to precipitate Al(OH)3 particles having a soda content of <=500ppm in terms of Na, a silica content of <=40ppm in terms of Si and a boehmite conversion ratio of <=25%. The Al(OH)3 particles are incorporated with 0.1-8.0wt.% (based on the total crushing component) of alpha-Al2O3 having an average particle diameter of <=0.5mum as a seed. The mixture is crushed and classified to obtain a fraction having an average particle diameter of <=5Xm and containing <0.1wt.% (based on the total fraction) of particles having particle diameter of >=10mum. The Al(OH)3 particles are calcined at 1000-1200 deg.C for several min to ten odd hours, washed with hot water or a mineral acid to remove the soda component, dried and crushed to obtain an extremely easily sinterable Al2O3 having a BET specific surface area of >=10m<2>/g and consisting of the single phase of alpha-Al2O3.

Abstract: PROBLEM TO BE SOLVED: To provide an oxygen concentration-detecting apparatus which can restrict to a minimum affects due to the presence of an interruption period while an oxygen concentration detection is interrupted, with maintaining detection accuracy for the oxygen concentration. SOLUTION: When an internal resistance detection cycle time tmf reaches '0', a resistance detection flag FAFINH is set to '1' representing that it is a period to carry out an LAF (limiting current-type oxygen) sensor activation process (step S402), and it is judged whether or not the output current value I0 of the LAF sensor is larger than a reference value IREF (step S403). As a result of the judgment, if the I0 is larger than the IREF, a first cycle Tf1 (e.g. 128ms) is set to the resistance detection cycle timer tmf (step S404). On the other hand, when the I0 is not larger than the IREF, a second cycle Tf2 (e.g. 256ms) longer than the first cycle Tf1 is set to the timer tmf (step S405).
