西青電熔鎂砂主要有三大種類；一、普(pu)通電(dian)(dian)熔(rong)鎂砂，二(er)、低硅高鈣電(dian)(dian)熔(rong)鎂砂，三、大結(jie)晶電(dian)(dian)熔(rong)鎂砂；  

1、普通電熔鎂砂產品主要是選用47%以上含量菱鎂石或輕燒鎂砂為主要原料在電弧中高溫熔融而成。方鎂石晶粒大，結構致密，抗渣性強，高溫體積穩定性優越。電熔鎂砂的主要用途：電熔鎂砂主要是用于堿(jian)性磚、含碳制品和不定型耐(nai)火材料的良好(hao)原料。

 2、低(di)(di)硅(gui)(gui)高鈣(gai)電(dian)(dian)熔(rong)(rong)(rong)鎂砂產(chan)品主要(yao)是(shi)選用低(di)(di)硅(gui)(gui)菱(ling)鎂石為原(yuan)料，經高溫電(dian)(dian)熔(rong)(rong)(rong)爐熔(rong)(rong)(rong)煉而成的。其特點是(shi)鈣(gai)硅(gui)(gui)比(bi)大于 2 ，晶粒(li)發育充分(fen)，顆料體積密度大于 3.50g/cm3以上(shang)。低(di)(di)硅(gui)(gui)高鈣(gai)點熔(rong)(rong)(rong)鎂砂主要(yao)用于中(zhong)頻(pin)感(gan)應電(dian)(dian)爐熔(rong)(rong)(rong)煉、高錳鋼(gang)、不(bu)銹鋼(gang)、高鑼鋼(gang)、堿性磚、含碳(tan)制品和不(bu)定型耐火材料的良好原(yuan)料。

3、大(da)結(jie)晶(jing)(jing)電(dian)(dian)熔(rong)鎂砂生(sheng)產(chan)工藝：大(da)結(jie)晶(jing)(jing)電(dian)(dian)熔(rong)鎂砂主要是(shi)選用(yong)精選的特級天然菱(ling)鎂石或優質高純(chun)輕燒鎂顆粒，在電(dian)(dian)弧爐中(zhong)熔(rong)融制得(de)。該產(chan)品具(ju)有(you)(you)(you)純(chun)度(du)高，結(jie)晶(jing)(jing)粒大(da)，結(jie)構致密，抗(kang)渣(zha)性(xing)(xing)強，熱(re)震(zhen)穩(wen)定性(xing)(xing)好，是(shi)一種優良的高溫(wen)(wen)電(dian)(dian)氣絕緣材料，也(ye)是(shi)制作鎂磚，鎂碳磚及不定型耐火材料的重要原料。廣泛應用(yong)于冶(ye)金、化(hua)工、國防(fang)、科研、航天航空、家用(yong)電(dian)(dian)器元件等。 大(da)結(jie)晶(jing)(jing)電(dian)(dian)熔(rong)鎂砂產(chan)品特性(xing)(xing)：純(chun)度(du)高、結(jie)晶(jing)(jing)粒大(da)熔(rong)、點高結(jie)、構致密；熱(re)震(zhen)穩(wen)定性(xing)(xing)好；具(ju)有(you)(you)(you)良好的高溫(wen)(wen)抗(kang)折強度(du)；具(ju)有(you)(you)(you)良好的抗(kang)渣(zha)性(xing)(xing)能(neng)和抗(kang)腐蝕性(xing)(xing)能(neng)；導熱(re)性(xing)(xing)能(neng)強、高度(du)絕緣。
