土狀石墨
土狀石墨也叫無定形石墨，變質程度深屬優質微晶石墨，絕大部分為石墨碳，顏色剛灰，有金屬光澤，質軟,莫氏硬度1－2，比重2－2.24,化學性質穩定，不受強酸堿影響，土狀石墨有害雜質少，鐵，硫，磷，氮，鉬,氫含量低。
土狀石墨按其產出形態可分為兩種：分散狀土狀石墨礦石和致密塊狀土狀石墨礦石。土狀石墨廣泛用于鑄造涂料，油田鉆井，電池炭棒、鋼鐵、鑄造材料、耐火材料、染料、燃料、電極糊、以及用作鉛筆、焊條、電池、石墨乳劑、脫硫劑、防腐劑防滑劑、冶煉增碳劑、注錠保護渣、石墨軸承等產品的配料.
amorphous graphite.，The degree of deterioration belongs to high-quality
microcrystalline graphite. Most of them are graphite carbon, color
rigid ash, metallic luster, soft, Mohs hardness 1-2, specific gravity
2-2.24. Their chemical properties are stable and not affected by strong
acid and alkali. Soil graphite has less harmful impurities, and low
contents of iron, sulfur, phosphorus, nitrogen, molybdenum and hydrogen.
Soil graphite can be divided into two types according to its output
form: dispersed soil graphite ore and dense massive soil graphite ore.
Soil graphite is widely used in foundry coatings, oil field drilling,
battery carbon rods, iron and steel, foundry materials, refractories,
dyes, fuels, electrode pastes, and as ingredients for pencils, welding
rods, batteries, graphite emulsions, desulfurizers, preservatives,
antiskid agents, smelting carburetors, ingot flux, graphite bearings and
other products.
