产品说明
产品参数

碳化硅是用石英砂、石油焦(或煤焦)、木屑(生产绿色碳化硅时需要加食盐) 等原料在电阻炉内经高温冶炼而成。

高純度綠碳化矽磨料硬度介于刚玉和金刚石之间，机械强度高于刚玉，硬度很大，性脆而锋利，具有优良的导热和导电性能，高温时能抗氧化。

碳化矽物理指標：碳化矽分爲黑色碳化矽和綠色碳化矽兩種，微觀形狀呈六方晶體，碳化矽的莫氏硬度爲9.5，威氏顯微密硬度爲3000--3300公斤/毫米，努普硬度爲2670—2815公斤/毫米，顯微硬度3300千克每立方毫米。密度一般認爲是3.20克/毫米3，其碳化矽磨料的自然堆積密度在1.2--1.6克/毫米3之間，比重爲3.20～3.25。

He appeared to be addressing the air generally. "There," she whispered. "Take them. It is the bitterest moment of my life for----" Constantly new and large transports of wounded came along the road, and here and there they were busy killing and burying wounded horses. The inhabitants locked themselves in their houses, and expected with great fear that any moment the military might arrive to claim their last horse or cow. The requisitions went on continuously, and the cattle were driven to the front in a long, desolate procession. Deftly Jeff caught the skid. One little thing bothered Sandy at that point in his musing: why had Jeff not made away with the life preserver at once? "You don't love her, for that matter, either," Mrs. Campbell reminded him. But she advised the inevitable,—to wait and let it work itself out. "You're a devil of a way from home, and in a bad neighborhood," said one of the men who had fired, as he slipped another cartridge into his Sharpe's. "Apparently," said the busy Surgeon, stopping for a minute, with knife and bullet-forceps in his bloodstained hands, to give a brief glance and two or three swift touches to Gid, "the ball has struck his side and broke a rib or two. He's swooned from loss of blood. The blood's stopped flowing now, and he'll come around all right. Lay him over there in the shade of those trees. Put something under his head, and make him as comfortable as possible. I'll attend to him as soon as I can get through with these men who are much worse off than he is." Moves me to passion I can scarce control, "Git out of this!" he shouted. "I w?an't stand here and listen to you miscalling the farm wot's bred you and fed you over thirty year. Git out, and never think you'll come back again. I'm shut of you. I d?an't want no more of you—I'm out of the wood now, I've got all the work out of you I've needed, so you can go, and spread your hemmed Word, and be hemmed. I'm shut of you."
