Phapang pakeng tsa phofo e tšoeu ea corundum le phofo ea alumina

Phofo e tšoeu ea corundum le phofo ea alumina e na le ponahalo e tšoanang le mabitso a tšoanang. Batho ba bangata ba batla ho hlakisa phapang pakeng tsa bona. Qianjiaxin Refractories e latelang e tla e khetholla ho tsoa ho sebopeho sa eona.
